Trail Ridge Road
–
Trail Ridge Road is the name for a stretch of U. S. Highway 34 that traverses Rocky Mountain National Park from Estes Park, Colorado in the east to Grand Lake, Colorado in the west. It requires access to Rocky Mountain National Park even for local residents, from Kawuneeche Visitor Center at the parks Grand Lake Entrance, Trail Ridge Road follows the North Fork of the Colorado River north through the Kawuneeche Valley. There are several trailheads along this section of the road, notably the Colorado River Trailhead, the road crosses the Continental Divide at Milner Pass and reaches a maximum elevation of 12,183 ft, near Fall River Pass. Near the highest point on the road is another pass, Iceberg Pass, according to construction contracts and park maintenance files the east end of the road is located at the Fall River Entrance, however some guides state that earlier - at Deer Ridge Junction. Trail Ridge is a flat spur range extending east from the main range of the Rockies between Fall River in the North and the Big Thompson River in the South. The road follows Trail Ridge from the Fall River Pass near Alpine Visitor Center to the Deer Ridge Junction, Fall River Road was the first road into the parks high country. It opened in 1921 and quickly proved inadequate for motor travel as a road with steep grades, tight curves. Construction began in 1929 and was complete to Fall River Pass by July 1932, the road was complete through the Kawuneeche Valley to Grand Lake in 1938. The route followed what was known to local Arapaho Indians as the Dog Trail, internal opposition to the construction of a road through the parks alpine tundra was overruled by National Park Service director Horace Albright, who wished to encourage park visitation. The road was designed to intrude as little as possible into the landscape, hidden Valley was a local ski area attraction from 1955 -1991, off of Trail Ridge Road, now in defunct status. Trail Ridge had been used by Native Americans to cross the mountains between their lands in the west and hunting areas on the east side. Arapahoe Indians called the trail located on the ridge as taienbaa because it was so steep that children could not be carried, the Ute tribe crossing the mountains at Forest Canyon Pass marked their route with stone cairns. The present park Ute Trail follows partially that ancient route, on the west side, about 1880, a wagon road was constructed along the Kawuneeche Valley from the town of Grand Lake to the mining camps of Lulu City and Gaskil. The camps were abandoned after a few years when short-lived mining boom ended and later the road was used occasionally by hunters

Summit
–
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically, a summit is a maximum in elevation. The topographic terms acme, apex, peak, and zenith are synonymous, the UIAA definition is that a summit is independent if it has a prominence of 30 metres or more, it is a mountain if it has a prominence of at least 300 metres. This can be summarised as follows, A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top, Summit may also refer to the highest point along a line, trail, or route. In many parts of the western United States, the term refers to the highest point along a road, highway. For example, the highest point along Interstate 80 in California is referred to as Donner Summit while the highest point on Interstate 5 is Siskiyou Mountain Summit, geoid Hill List of highest mountains Maxima and minima Nadir Summit accordance Peak finder

Topographic prominence
–
It is a measure of the independence of a summit. A peaks key col is a point on this contour line. By convention, the prominence of Mount Everest, the Earths highest mountain, is taken to equal the elevation of its summit above sea level, if the peaks prominence is P metres, to get from the summit to any higher terrain one must descend at least P metres. Together with the convention for Mount Everest, this implies that the prominence of any island or continental highpoint is equal to its elevation above sea level, for every ridge connecting the peak to higher terrain, find the lowest point on the ridge. The key col is defined as the highest of these cols, the prominence is the difference between the elevation of the peak and the elevation of the key col. The following mental exercise may illustrate the meaning of topographic prominence, imagine you are standing at the top of a peak and imagine that an imaginary sea level rises to your feet. Now slowly lower the sea level and an imaginary island appears beneath your feet. Your island will grow and will merge with other islands that emerge, the parent peak may be either close or far from the subject peak. The summit of Mount Everest is the parent peak of Aconcagua at a distance of 17,755 km, the key col may also be close or far from the subject peak. The key col for Aconcagua is the Bering Strait at a distance of 13,655 km, the key col for the South Summit of Mount Everest is about 100 m distant. Prominence is interesting to many mountaineers because it is a measurement that is strongly correlated with the subjective significance of a summit. Peaks with low prominences are either subsidiary tops of some higher summit or relatively insignificant independent summits, peaks with high prominences tend to be the highest points around and are likely to have extraordinary views. Only summits with a sufficient degree of prominence are regarded as independent mountains, for example, the worlds second-highest mountain is K2. While Mount Everests South Summit is taller than K2, it is not considered an independent mountain because it is a subsummit of the main summit, many lists of mountains take topographic prominence as a criterion for inclusion, or cutoff. John and Anne Nuttalls The Mountains of England and Wales uses a cutoff of 15 m, in the contiguous United States, the famous list of fourteeners uses a cutoff of 300 ft /91 m. Also in the U. S.2000 feet of prominence has become a threshold that signifies that a peak has major stature. This generates lists of peaks ranked by prominence, which are different from lists ranked by elevation. Such lists tend to emphasize isolated high peaks, such as range or island high points, one advantage of a prominence-ranked list is that it needs no cutoff, since a peak with high prominence is automatically an independent peak

Red triangles mark the peaks, the lowest contour line encircling each peak are shown in black and the green dots mark the key cols. The prominences are Atkins Hill: 430 – 310 = 120 ft, Cave Hill: 570 - 530 = 40 ft, Mead Mountain: 671 - 530 = 141 ft. The parent peak of each peak is Great Pond Mountain.

Topographic isolation
–
The topographic isolation of a summit is the minimum great-circle distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point. It can be calculated for small hills and islands as well as for major mountain peaks, the following sortable table lists the Earths 40 most topographically isolated summits. The nearest peak to Germanys highest mountain, the 2, 962-metre-high Zugspitze, the distance between the Zugspitze and this contour is 25.8 km, the Zugspitze is thus the highest peak for a radius of 25.8 km around. Its isolation is thus 25.8 km, because there are no higher mountains than Mount Everest, it has no definitive isolation. Many sources list its isolation as the circumference of the earth over the poles or – questionably, after Mount Everest the Aconcagua, highest mountain of the American continents, has the greatest isolation of all mountains. There is no land for 16,534 kilometres when its height is first exceeded by Tirich Mir in the Hindu Kush. Mont Blanc is the highest mountain of the Alps, the geographically nearest higher mountains are all in the Caucasus. The Kukurtlu, which rises near the Elbrus, is the peak for Mont Blanc. com Canadian Mountain Encyclopedia peakbagger. com peaklist. org peakware. com World Mountain Encyclopedia summitpost. org

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Colorado
–
Colorado is a state in the United States encompassing most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is part of the Western United States, the Southwestern United States, Colorado is the 8th most extensive and the 21st most populous of the 50 United States. The United States Census Bureau estimates that the population of Colorado was 5,540,545 on July 1,2016, the state was named for the Colorado River, which Spanish travelers named the Río Colorado for the ruddy silt the river carried from the mountains. The Territory of Colorado was organized on February 28,1861, Colorado is nicknamed the Centennial State because it became a state in the same year as the centennial of the United States Declaration of Independence. Colorado is noted for its landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers. Denver is the capital and the most populous city of Colorado, residents of the state are properly known as Coloradans, although the term Coloradoan has been used archaically and lives on in the title of Fort Collins newspaper, the Coloradoan. Colorado, Wyoming and Utah are the states which have boundaries defined solely by lines of latitude and longitude. The summit of Mount Elbert at 14,440 feet elevation in Lake County is the highest point in Colorado, Colorado is the only U. S. state that lies entirely above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County, Colorado and this point, which holds the distinction of being the highest low elevation point of any state, is higher than the high elevation points of 18 states and the District of Columbia. A little less than one half of the area of Colorado is flat, East of the Rocky Mountains are the Colorado Eastern Plains of the High Plains, the section of the Great Plains within Nebraska at elevations ranging from roughly 3,350 to 7,500 feet. The Colorado plains were mostly prairies, but they have many patches of forests, buttes. Eastern Colorado is presently covered in farmland and rangeland, along with small farming villages. Precipitation is fair, averaging from 15 to 25 inches annually, corn, wheat, hay, soybeans, and oats are all typical crops, and most of the villages and towns in this region boast both a water tower and a grain elevator. Irrigation water is available from the South Platte, the Arkansas River, and a few other streams, however, heavy use of ground water from wells for irrigation has caused underground water reserves to decline. As well as agriculture, eastern Colorado hosts considerable livestock, such as cattle ranches. Roughly 70% of Colorados population resides along the edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne, Wyoming, and Pueblo, Colorado. This region is protected from prevailing storms that blow in from the Pacific Ocean region by the high Rockies in the middle of Colorado. The Front Range includes Denver, Boulder, Fort Collins, Loveland, Colorado Springs, Pueblo, Greeley and other townships, on the other side of the Rockies, the significant population centers in Western Colorado are the cities of Grand Junction, Durango, and Montrose

Rocky Mountain National Park
–
The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and westerns slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the northwestern region. The main features of the park include mountains, alpine lakes, the Rocky Mountain National Park Act was signed by then–President Woodrow Wilson on January 26,1915, establishing the park boundaries and protecting the area for future generations. The Civilian Conservation Corps built the main route, named Trail Ridge Road. In 1976, UNESCO designated the park as one of the first World Biosphere Reserves, in 2016, more than four and a half million recreational visitors entered the park, which is an increase of about nine percent from the prior year. The history of Rocky Mountain National Park began when Paleo-Indians traveled along what is now Trail Ridge Road to hunt, Ute and Arapaho people subsequently hunted and camped in the area. In 1820, the Long Expedition, led by Stephen H. Long for whom Longs Peak was named, approached the Rockies via the Platte River. Settlers began arriving in the mid-1800s, displacing the Native Americans who mostly left the area voluntarily by 1860, lulu City, Dutchtown, and Gaskill in the Never Summer Mountains were established in the 1870s when prospectors came in search of gold and silver. The boom ended by 1883 with miners deserting their claims, the railroad reached Lyons, Colorado in 1881 and the Big Thompson Canyon Road—a section of U. S. Route 34 from Loveland to Estes Park—was completed in 1904. The 1920s saw a boom in building lodges and roads in the park, prominent individuals in the effort to create a national park included Enos Mills from the Estes Park area, James Grafton Rogers from Denver, and J. Horace McFarland of Pennsylvania. The national park was established on January 26,1915, Precambrian metamorphic rock formed the core of the North American continent during the Precambrian eon 4. 5–1 billion years ago. During the Paleozoic era, western North America was submerged beneath a sea, with a seabed composed of limestone. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime, eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin. About 300 million years ago, the land was uplifted creating the ancestral Rocky Mountains, fountain Formation was deposited during the Pennsylvanian period of the Paleozoic era, 290–296 million years ago. Over the next 150 million years, the uplifted, continued to erode. Wind, gravity, rainwater, snow, and glacial ice eroded the mountains over geologic time scales. The Ancestral Rockies were eventually buried under subsequent strata, the Pierre Shale formation was deposited during the Paleogene and Cretaceous periods about 70 million years ago. The region was covered by a deep sea—the Cretaceous Western Interior Seaway—which deposited massive amounts of shale on the seabed

Larimer County, Colorado
–
Larimer County is one of the 64 counties in the U. S. state of Colorado. As of the 2010 census, the population was 299,630, the county seat and most populous city is Fort Collins. The county was named for William Larimer, Jr. the founder of Denver, Larimer County comprises the Fort Collins, CO Metropolitan Statistical Area. The county is located at the end of the Front Range. Larimer County was created in 1861 as one of seventeen counties in the Colorado Territory, however. Controversy existed as to whether Larimer County ended at the Medicine Bow Range or at the Continental Divide thirty miles farther west. An 1886 Colorado Supreme Court decision set the boundary at the Continental Divide, the mining boom almost entirely passed the county by. It would take the introduction of irrigation to the region in the 1860s to bring the first widespread settlement to the area, in 1828 William H. Ashley ascended the Cache la Poudre River on his way to the Green River in present-day Utah. The river itself received its name in the middle 1830s from an incident in which French-speaking trappers hid gunpowder along its banks. In 1848 a group of Cherokee crossed through the county following the North Fork of the Poudre to the Laramie Plains on their way to California along a route that became known as the Cherokee Trail. The first U. S. settlers arrived that year in a party led by Antoine Janis from Fort Laramie. Nearly simultaneously, Mariano Medina established Fort Namaqua along the Big Thompson River just west of present-day Loveland, the first irrigation canals were established along the Poudre in the 1860s. In 1861, Laporte was designated as the first county seat after the organization of the Colorado Territory, in 1862, the United States Army established an outpost near Laporte that was designated as Camp Collins. A devastating flood in June 1864 wiped out the outpost, forcing the Army to seek a better location, at the urging of Joseph Mason, who had settled along the Poudre in 1860, the Army relocated its post downstream adjacent to Masons land along the Overland stage route. The site of the new post became the nucleus of the town of Fort Collins, by that time, Mason and others had convinced the Colorado Territorial Legislature to designate the new town as the county seat. Cameron and other members of the Greeley Colony established the Fort Collins Agricultural Colony, one of the primary goals of the early citizens of the county was the courting of railroads. County residents were disappointed when the Denver Pacific Railroad bypassed the county in 1870 in favor of Greeley, the first railroad finally arrived in the county in 1877 when the Colorado Central Railroad extended a line north from Golden via Longmont to Cheyenne. The town council of Fort Collins designated right-of-way through the center of town for the line, along the new railroad sprung up the new platted towns of Loveland and Berthoud, named respectively after the president and chief surveyor of the Colorado Central

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Mountain range
–
A mountain range is a geographic area containing numerous geologically related mountains. A mountain system or system of ranges, sometimes is used to combine several geological features that are geographically related. Mountain ranges are usually segmented by highlands or mountain passes and valleys, individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, most geologically young mountain ranges on the Earths land surface are associated with either the Pacific Ring of Fire or the Alpide Belt. The Andes is 7,000 kilometres long and is considered the worlds longest mountain system. The Alpide belt includes Indonesia and southeast Asia, through the Himalaya, the belt also includes other European and Asian mountain ranges. The Himalayas contain the highest mountains in the world, including Mount Everest, mountain ranges outside of these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Altai Mountains and the Hijaz Mountains. If the definition of a range is stretched to include underwater mountains. The mountain systems of the earth are characterized by a tree structure, the sub-range relationship is often expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains, equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, and the White Mountains and the Blue Ridge Mountains are children of the Appalachians. The position of mountains influences climate, such as rain or snow, when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the side, it warms again and is drier. Often, a shadow will affect the leeward side of a range. Mountain ranges are constantly subjected to forces which work to tear them down. Erosion is at work while the mountains are being uplifted and long after until the mountains are reduced to low hills, rivers are traditionally believed to be the principle erosive factor on mountain ranges, with their ability of bedrock incision and sediment transport. The rugged topography of a range is the product of erosion. The basins adjacent to a mountain range are filled with sediments which are buried and turned into sedimentary rock. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example and this mass of rock was removed as the range was actively undergoing uplift

Front Range
–
It is the first mountain range encountered moving west along the 40th parallel north across the Great Plains of North America. The Front Range runs north-south between Casper, Wyoming and Pueblo, Colorado and rises nearly 10,000 feet above the Great Plains, Longs Peak, Mount Evans, and Pikes Peak are its most prominent peaks, visible from the Interstate 25 corridor. The area is a destination for mountain biking, hiking, climbing. Millions of years ago the present-day Front Range was home to ancient mountain ranges, deserts, beaches and this urban corridor benefits from the weather-moderating effect of the Front Range mountains, which help block prevailing storms. About 1 billion years ago, the earth was producing massive amounts of rock that would one day amalgamate, drift together and combine. In the Colorado region, this molten rock spewed and cooled, over the next 500 million years, little is known about changes in the sedimentation after the granite was produced. However, at about 500 –300 million years ago, the region began to sink, eroded granite produced sand particles that began to form strata, layers of sediment, in the sinking basin. Sedimentation would continue to place until about 300 million years ago. Around 300 million years ago, the sinking suddenly reversed, over the next 150 million years, during uplift the mountains would continue to erode and cover themselves in their own sediment. Wind, gravity, rainwater, snow, and ice-melt supplied rivers that ultimately carved through the granite mountains, the sediment from these mountains lies in the Fountain Formation today. Red Rocks Amphitheater outside of Denver, Colorado, is set into the Fountain Formation. At 280 million years ago, sea levels were low and present-day Colorado was part of the super-continent Pangaea, sand deserts covered most of the area spreading as dunes seen in the rock record, known today as the Lyons Sandstone. These dunes appear to be cross-bedded and show various fossil footprints,30 million years later, the sediment deposition was still taking place with the introduction of the Lykins Formation. This formation can be best attributed to its layers of muddy limestone. 250 million years ago, the Ancestral Rockies were burying themselves while the shoreline was present during the break-up of Pangaea and this formation began right after Earth’s largest extinction 251 million years ago at the Permian-Triassic Boundary. Ninety percent of the marine life was destroyed and a great deal on land as well. After 100 million years of deposition, a new environment brought rise to a new formation, the Morrison Formation contains some of the best fossils of the Late Jurassic. It is especially known for its tracks and sauropod bones among other dinosaur fossils

Topographic map
–
Traditional definitions require a topographic map to show both natural and man-made features. A topographic map is published as a map series, made up of two or more map sheets that combine to form the whole map. A contour line is a line connecting places of equal elevation, however, in the vernacular and day to day world, the representation of relief is popularly held to define the genre, such that even small-scale maps showing relief are commonly called topographic. The study or discipline of topography is a broader field of study. Topographic maps are based on topographical surveys, performed at large scales, these surveys are called topographical in the old sense of topography, showing a variety of elevations and landforms. This is in contrast to older cadastral surveys, which primarily show property, the first multi-sheet topographic map series of an entire country, the Carte géométrique de la France, was completed in 1789. Topographic surveys were prepared by the military to assist in planning for battle, as such, elevation information was of vital importance. As they evolved, topographic map series became a resource in modern nations in planning infrastructure. Excluding borders, each sheet was 44 cm high and up to 66 cm wide, although the project eventually foundered, it left an indexing system that remains in use. TIGER was developed in the 1980s and used in the 1990, digital elevation models were also compiled, initially from topographic maps and stereographic interpretation of aerial photographs and then from satellite photography and radar data. Since all these were government projects funded with taxes and not classified for security reasons. Initial applications were mostly professionalized forms such as innovative surveying instruments, by the mid-1990s, increasingly user-friendly resources such as online mapping in two and three dimensions, integration of GPS with mobile phones and automotive navigation systems appeared. As of 2011, the future of standardized, centrally printed topographical maps is left somewhat in doubt, the various features shown on the map are represented by conventional signs or symbols. For example, colors can be used to indicate a classification of roads and these signs are usually explained in the margin of the map, or on a separately published characteristic sheet. Topographic maps are commonly called contour maps or topo maps. In the United States, where the national series is organized by a strict 7. 5-minute grid. Topographic maps conventionally show topography, or land contours, by means of contour lines, contour lines are curves that connect contiguous points of the same altitude. In other words, every point on the line of 100 m elevation is 100 m above mean sea level

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its resources. The organization has four science disciplines, concerning biology, geography, geology. The USGS is a research organization with no regulatory responsibility. The USGS is a bureau of the United States Department of the Interior, the USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, the current motto of the USGS, in use since August 1997, is science for a changing world. The agencys previous slogan, adopted on the occasion of its anniversary, was Earth Science in the Public Service. Prompted by a report from the National Academy of Sciences, the USGS was created, by a last-minute amendment and it was charged with the classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain. This task was driven by the need to inventory the vast lands added to the United States by the Louisiana Purchase in 1803, the legislation also provided that the Hayden, Powell, and Wheeler surveys be discontinued as of June 30,1879. Clarence King, the first director of USGS, assembled the new organization from disparate regional survey agencies, after a short tenure, King was succeeded in the directors chair by John Wesley Powell. Administratively, it is divided into a Headquarters unit and six Regional Units, Other specific programs include, Earthquake Hazards Program monitors earthquake activity worldwide. The National Earthquake Information Center in Golden, Colorado on the campus of the Colorado School of Mines detects the location, the USGS also runs or supports several regional monitoring networks in the United States under the umbrella of the Advanced National Seismic System. The USGS informs authorities, emergency responders, the media, and it also maintains long-term archives of earthquake data for scientific and engineering research. It also conducts and supports research on long-term seismic hazards, USGS has released the UCERF California earthquake forecast. The USGS National Geomagnetism Program monitors the magnetic field at magnetic observatories and distributes magnetometer data in real time, the USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data are available online, since 1962, the Astrogeology Research Program has been involved in global, lunar, and planetary exploration and mapping. USGS operates a number of related programs, notably the National Streamflow Information Program. USGS Water data is available from their National Water Information System database

Scrambling
–
Scrambling is a walk up steep terrain involving the use of ones hands. It is a term that lies somewhere between hiking, hillwalking, mountaineering, and easy rock climbing. Alpine scrambling is a term applied to scrambling in high mountains like the Alps and the Rockies of North America, the Mountaineers climbing organization defines alpine scrambling as follows, Alpine Scrambles are off-trail trips, often on snow or rock, with a non-technical summit as a destination. A non-technical summit is one that is reached without the need for certain types of climbing equipment, however, this can mean negotiating lower angle rock, traveling through talus and scree, crossing streams, fighting ones way through dense brush, and walking on snow-covered slopes. Although ropes may be sensible on harder scrambles, sustained use of rope and belay counts as climbing, typically, for this reason mountain walkers are advised to carry a rope on harder scrambles. Scramblers are also advised to know their limits and to turn back before they get into difficulties, some mountain tops may be reached by walking or scrambling up their least-steep side. The essence of a modern via ferrata is a cable which runs along the route and is periodically fixed to the rock. Using a via ferrata kit, climbers can secure themselves to the cable, the cable can also be used as aid to climbing, and additional climbing aids, such as iron rungs, pegs, carved steps and even ladders and bridges are often provided. Thus via ferratas allow otherwise dangerous routes to be undertaken without the associated with unprotected scrambling and climbing or the need for climbing equipment such as ropes. Many of theses routes include a bad step, where the scrambling suddenly becomes more serious. The bad step on Crib Goch for example, involves only 20 feet or so of climbing, the rock face here is well polished by countless boots, but there are many holds which offer firm support. By contrast, the traverse of the Cuillin Ridge on Skye demands use of a rope at one point at least, the ridge routes of Liathach and Beinn Eighe in Wester Ross are easier to traverse but are extremely exposed. Descent from such ridges is very limited, so once committed, an Teallach to the north offers scrambling, as does Stac Pollaidh further north in Sutherland, which includes a bad step. One resource for scramblers in Britain are the guides by W A Poucher, though these are now dated, a guide to 156 scrambling routes in the Canadian Rockies can be found in Scrambles in the Canadian Rockies by Alan Kane. Backpacker magazine has featured the book as an expedition guide. The Canadian Alpine Journal referred to it as a scree gospel, mount Jefferson is in Coos County, New Hampshire, and is the third highest mountain in the state. Mount Jefferson has a direct ascent along the Caps Ridge Trail, whose base and this route, gaining only 2,700 feet vertically to the summit, makes for the easiest ascent of any Presidential mountain. However, climbing over the caps involves some exposed scrambling and can be steep, many easy scrambles become serious climbs in bad weather

A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism and these forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, a few mountains are isolated summits, but most occur in huge mountain ranges. High elevations on mountains produce colder climates than at sea level and these colder climates strongly affect the ecosystems of mountains, different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, the highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m, there is no universally accepted definition of a mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain, whether a landform is called a mountain may depend on local usage. The highest point in San Francisco, California, is called Mount Davidson, notwithstanding its height of 300 m, similarly, Mount Scott outside Lawton, Oklahoma is only 251 m from its base to its highest point. Whittows Dictionary of Physical Geography states Some authorities regard eminences above 600 metres as mountains, in addition, some definitions also include a topographical prominence requirement, typically 100 or 500 feet. For a while, the US defined a mountain as being 1,000 feet or taller, any similar landform lower than this height was considered a hill. However, today, the United States Geological Survey concludes that these terms do not have technical definitions in the US, using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As a whole, 24% of the Earths land mass is mountainous, there are three main types of mountains, volcanic, fold, and block. All three types are formed from plate tectonics, when portions of the Earths crust move, crumple, compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of the feature makes it either a hill or, if higher and steeper, major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Volcanoes are formed when a plate is pushed below another plate, at a depth of around 100 km, melting occurs in rock above the slab, and forms magma that reaches the surface. When the magma reaches the surface, it builds a volcanic mountain. Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines, the magma does not have to reach the surface in order to create a mountain, magma that solidifies below ground can still form dome mountains, such as Navajo Mountain in the US

Rocky Mountains

The Rocky Mountains, commonly known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than 3,000 miles from the northernmost part of British Columbia, in western Canada, to New Mexico, in the Southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges, the Rocky Mountains were initially formed from 80 million to 55 million years ago during the Laramide orogeny, in which a number of plates began to slide underneath the North American plate. The angle of subduction was shallow, resulting in a belt of mountains running down western North America. Since then, further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks, at the end of the last ice age, humans started to inhabit the mountain range. The first mention of their present name by a European was in the journal of Jacques Legardeur de Saint-Pierre in 1752, the Rocky Mountains are commonly defined as stretching from the Liard River in British Columbia south to the Rio Grande in New Mexico. The United States definition of the Rockies includes the Cabinet and Salish Mountains of Idaho and their counterparts north of the Kootenai River, the Columbia Mountains, are considered a separate system in Canada, lying to the west of the huge Rocky Mountain Trench. This runs the length of British Columbia from its beginnings in the middle Flathead River valley in western Montana to the bank of the Liard River. The Rockies vary in width from 70 to 300 miles, also west of the Rocky Mountain Trench, farther north and facing the Muskwa Range across the trench, are the Stikine Ranges and Omineca Mountains of the Interior Mountains system of British Columbia. A small area east of Prince George, British Columbia on the side of the Trench. In Canada geographers define three main groups of ranges, the Continental Ranges, Hart Ranges and Muskwa Ranges, the Muskwa and Hart Ranges together comprise what is known as the Northern Rockies. The western edge of the Rockies includes ranges such as the Wasatch near Salt Lake City, the Great Basin and Columbia River Plateau separate these sub-ranges from distinct ranges further to the west, most prominent among which are the Sierra Nevada, Cascade Range and Coast Mountains. The Rocky Mountain System within the United States is a United States physiographic region, the Rocky Mountains are notable for containing the highest peaks in central North America. The ranges highest peak is Mount Elbert located in Colorado at 14,440 feet above sea level, Mount Robson in British Columbia, at 12,972 feet, is the highest peak in the Canadian Rockies. The Continental Divide of the Americas is located in the Rocky Mountains, triple Divide Peak in Glacier National Park is so named because water that falls on the mountain reaches not only the Atlantic and Pacific, but Hudson Bay as well. Farther north in Alberta, the Athabasca and other rivers feed the basin of the Mackenzie River, see Rivers of the Rocky Mountains for a list of rivers. Human population is not very dense in the Rocky Mountains, with an average of four people per square kilometer, however, the human population grew rapidly in the Rocky Mountain states between 1950 and 1990. The 40-year statewide increases in range from 35% in Montana to about 150% in Utah

North America

North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16. 5% of the land area. North America is the third largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 565 million people in 23 independent states, or about 7. 5% of the worlds population, North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago, the Classic stage spans roughly the 6th to 13th centuries. The Pre-Columbian era ended with the migrations and the arrival of European settlers during the Age of Discovery. Present-day cultural and ethnic patterns reflect different kind of interactions between European colonists, indigenous peoples, African slaves and their descendants, European influences are strongest in the northern parts of the continent while indigenous and African influences are relatively stronger in the south. Because of the history of colonialism, most North Americans speak English, Spanish or French, the Americas are usually accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass previously unknown by Europeans. In 1507, Waldseemüller produced a map, in which he placed the word America on the continent of South America. He explained the rationale for the name in the accompanying book Cosmographiae Introductio, for Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespuccis name, but in its feminine form America, following the examples of Europa, Asia and Africa. Later, other mapmakers extended the name America to the continent, In 1538. Some argue that the convention is to use the surname for naming discoveries except in the case of royalty, a minutely explored belief that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic name of Amairick. Another is that the name is rooted in a Native American language, the term North America maintains various definitions in accordance with location and context. In Canadian English, North America may be used to refer to the United States, alternatively, usage sometimes includes Greenland and Mexico, as well as offshore islands

Rocky Mountain National Park Wilderness
–
The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and westerns slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the northwestern region. The main features of the park include mountains, alpine lakes, the Rocky Mountain National Park Act was signed by then–President Woodrow Wilson on January 26,1915, establishing the park boundaries and protecting the area for future generations. The Civilian Conservation Corps built the main route, named Trail Ridge Road. In 1976, UNESCO designated the park as one of the first World Biosphere Reserves, in 2016, more than four and a half million recreational visitors entered the park, which is an increase of about nine percent from the prior year. The history of Rocky Mountain National Park began when Paleo-Indians traveled along what is now Trail Ridge Road to hunt, Ute and Arapaho people subsequently hunted and camped in the area. In 1820, the Long Expedition, led by Stephen H. Long for whom Longs Peak was named, approached the Rockies via the Platte River. Settlers began arriving in the mid-1800s, displacing the Native Americans who mostly left the area voluntarily by 1860, lulu City, Dutchtown, and Gaskill in the Never Summer Mountains were established in the 1870s when prospectors came in search of gold and silver. The boom ended by 1883 with miners deserting their claims, the railroad reached Lyons, Colorado in 1881 and the Big Thompson Canyon Road—a section of U. S. Route 34 from Loveland to Estes Park—was completed in 1904. The 1920s saw a boom in building lodges and roads in the park, prominent individuals in the effort to create a national park included Enos Mills from the Estes Park area, James Grafton Rogers from Denver, and J. Horace McFarland of Pennsylvania. The national park was established on January 26,1915, Precambrian metamorphic rock formed the core of the North American continent during the Precambrian eon 4. 5–1 billion years ago. During the Paleozoic era, western North America was submerged beneath a sea, with a seabed composed of limestone. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime, eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin. About 300 million years ago, the land was uplifted creating the ancestral Rocky Mountains, fountain Formation was deposited during the Pennsylvanian period of the Paleozoic era, 290–296 million years ago. Over the next 150 million years, the uplifted, continued to erode. Wind, gravity, rainwater, snow, and glacial ice eroded the mountains over geologic time scales. The Ancestral Rockies were eventually buried under subsequent strata, the Pierre Shale formation was deposited during the Paleogene and Cretaceous periods about 70 million years ago. The region was covered by a deep sea—the Cretaceous Western Interior Seaway—which deposited massive amounts of shale on the seabed

Estes Park, Colorado

The Town of Estes Park /ˈɛstɪs/ is a statutory town in Larimer County, Colorado, United States. A popular summer resort and the location of the headquarters for Rocky Mountain National Park, Estes Park had a population of 5,858 at the 2010 census. The town overlooks Lake Estes and Olympus Dam, before Europeans came to the Estes Park valley, the Arapaho Indians lived there in the summertime and called the valley the Circle. When three elderly Arapahoes visited Estes Park in 1914, they pointed out sites they remembered from their younger days, toll, recorder, and David Robert Hawkins, a Princeton student. In the 1850s, the Arapaho had spent summers camped around Marys Lake, where their rock fireplaces, tipi sites and they also recalled building eagle traps atop Longs Peak to get the war feathers coveted by all tribes. They remembered their routes to and from the valley in detail, naming trails and they pointed out the site of their buffalo trap, and described the use of dogs to pack meat out of the valley. Their recollections included a battle with Apaches in the 1850s, and fights with Utes who came to the area to hunt bighorn sheep, whites probably came into the Estes Park valley before the 1850s as trappers, but did not stay long. The town is named after Missouri native Joel Estes, who founded the community in 1859, Estes moved his family there in 1863. One of Estes early visitors was William Byers, an editor who wrote of his ascent of Longs Peak in 1864. Griff Evans and his came to Estes Park in 1867 to act as caretakers for the former Estes ranch. Recognizing the potential for tourism, he began building cabins to accommodate travelers, soon it was known as the first dude ranch in Estes Park, with guides for hunting, fishing, and mountaineering. Lord Dunravens land grab didnt work, but he controlled 6,000 acres before he changed tactics and opened the areas first resort, the Estes Park Hotel, in 1873, Englishwoman Isabella Bird, the daughter of an Anglican minister, came to the United States. Landing at San Francisco, she came overland to Colorado, where she borrowed a horse and set out to explore the Rocky Mountains with a guide, the notorious James Nugent, aka Rocky Mountain Jim. She wrote a memoir of their travels, including the ascent of Longs Peak. On June 19th 1874 Rocky Mountain Jim and neighbor Griff Evans had an argument, having had bitter history with each other, Nugent and Evans hated each other and were deep personal rivals when it came to tour guiding tourists. The argument escalated until Evans blasted Jim in the head with his rifle shotgun, Evans then traveled to Fort Collins to file an assault charge against Nugent, but he was arrested and tried for first degree murder when Jim Nugent died on September 9th 1874 of the bullet wound. Evans was put on trial, but the case was dismissed due to the lack of witnesses to the shooting. On August 9th 1875, the Loveland court-house acquitted Evans of any charges in the case, William Henry Jackson photographed Estes Park in 1873

Sea Level Datum of 1929
–
The Sea Level Datum of 1929 was the vertical control datum established for vertical control surveying in the United States of America by the General Adjustment of 1929. The datum was used to measure elevation above, and depression below, Mean sea level was measured at 26 tide gauges,21 in the United States and 5 in Canada. The datum was defined by the heights of mean sea level at the 26 tide gauges. The adjustment required a total of 66,315 miles of leveling with 246 closed circuits and 25 circuits at sea level. Since the Sea Level Datum of 1929 was a model, it was not a pure model of mean sea level. Therefore, it was renamed the National Geodetic Vertical Datum of 1929 in 1973, altitude Datum Geodesy Mean sea level North American Vertical Datum of 1988 Storm Surge Topographic elevation Topography Reference ellipsoid Geoid United States Geological Survey home page.

North American Vertical Datum of 1988

NAVD88 was established in 1991 by the minimum-constraint adjustment of geodetic leveling observations in Canada, the United States, and Mexico. It held fixed the height of the tidal bench mark, referenced to the International Great Lakes Datum of 1985 local mean sea level height value, at Rimouski, Quebec. The definition of NAVD88 uses the Helmert orthometric height, which calculates the location of the geoid from modeled local gravity, the NAVD88 model is based on then-available measurements, and remains fixed despite later improved geoid models. NAVD88 replaced the National Geodetic Vertical Datum of 1929, previously known as the Sea Level Datum of 1929, the elevation difference between points in a local area will show negligible change from one datum to the other, even though the elevation of both does change. NGVD29 used a model of gravity based on latitude to calculate the geoid and did not take into account other variations. Thus, the difference for points across the country does change between datums.

Geographic Names Information System
–
It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names to promote the standardization of feature names, the database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited, variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a permanent, unique feature record identifier, sometimes called the GNIS identifier, the database never removes an entry, except in cases of obvious duplication. The GNIS accepts proposals for new or changed names for U. S. geographical features, the general public can make proposals at the GNIS web site and can review the justifications and supporters of the proposals. The Bureau of the Census defines Census Designated Places as a subset of locations in the National Geographic Names Database, U. S. Postal Service Publication 28 gives standards for addressing mail. In this publication, the postal service defines two-letter state abbreviations, street identifiers such as boulevard and street, department of the Interior, U. S.

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Book Cliffs
–
The Book Cliffs are a series of desert mountains and cliffs in western Colorado and eastern Utah, in the western United States. They are so named because the cliffs of Cretaceous sandstone that cap many of the buttes appear similar to a shelf of books. Stretching nearly 200 miles from east to west, the Book Cliffs begin where the Colorado River descends south through De Beque Canyon into the Grand Valley to Price Canyon, the Book Cliffs appear mostly along the southern and western edge of the Tavaputs Plateau. The cliffs are composed of sedimentary materials. The Book Cliffs are within the Colorado Plateau geologic province, in the Colorado stretch of the Book Cliffs, abandoned coal mines are present, as significant coal resources were present in the region. These mines are now generally capped for safety, but several fatalities of recreational hikers have occurred at these mines since 1989. In some places, wild horses can be found in the Book Cliffs, for example, the Book Cliffs are one of the worlds best places to study sequence stratigraphy. In the 1980s, Exxon scientists used the Cretaceous strata of the Book Cliffs to develop the science of sequence stratigraphy. The Book Cliffs have preserved excellent strata of the basin of the ancient Western Interior Seaway that stretched north from the Gulf of Mexico to the Yukon in the Cretaceous time. Components of deltaic and shallow marine reservoirs are very well preserved in the Book Cliffs, large mammals found in the Book Cliffs include coyotes, mountain lions, bobcats, mule deer, pronghorn, American bison as an extension of the Henry Mountains bison herd and bighorn sheep. In January,2009, Utah Division of Wildlife Resources officials transplanted 31 bison from the Henry Mountains bison herd to the Book Cliffs, the new group joined 14 animals previously released in August,2008 from a private herd on the nearby Uintah and Ouray Indian Reservation. Since this herd is located approximately 100 miles north of the Henry Mountains, across mostly harsh, desert terrain, it should perhaps be considered as a separate herd, Cretaceous Paleogeography - Showing Western Interior Seaway The Soils of Western Colorado Mesa, Delta and Montrose Counties

Elk Mountains (Colorado)
–
The Elk Mountains are a high, rugged mountain range in the Rocky Mountains of west-central Colorado in the United States. The range sits west of the Sawatch Range and northeast of the West Elk Mountains, much of the range is located within the White River National Forest and the Gunnison National Forest, as well as the Maroon Bells-Snowmass Wilderness and Raggeds Wilderness. The Elk Mountains rise nearly 9,000 ft. above the Roaring Fork Valley to the north, the highest peaks in the range are its fourteeners, Castle Peak, Maroon Peak, Capitol Peak, Snowmass Mountain, Pyramid Peak, and North Maroon Peak. Maroon Peak and North Maroon Peak are collectively known as the Maroon Bells, mount Sopris sits at the northwest end of the range and dominates the skyline of the lower Roaring Fork Valley and the town of Carbondale, Colorado, serving as an unofficial symbol of the area. State Highway 133 traverses McClure Pass, at the end of the range. The range has been the site of mining activity since the days of the Colorado Silver Boom, in the late 19th century, the western and southern flank of the range became the site of intense coal mining activity which continues to the present day. Treasure Mountain, overlooking the town of Marble, is home to the famous Yule Marble Quarry, quarried marble was used to create The Tomb of the Unknowns, the Lincoln Memorial, Denver Post Office and other buildings. The range receives a great deal of snowfall due to its position to the west of the continental divide and this is exploited by the ski areas in the vicinity of Aspen, which are located on the flanks of smaller mountains alongside the Roaring Fork Valley

Aspen Mountain is a mountain summit in the Elk Mountains range of the Rocky Mountains of North America. The 10, 705-foot peak is located in White River National Forest,1.4 miles south-southeast of downtown Aspen in Pitkin County, Colorado, United States. The north face of the mountain is the location of the Aspen Mountain ski area, the mountain flank was the site of intense mining activity in the late 1880s and early 1890s, with many remains of mining activity below and on the surface of the mountain. In the middle 20th century it became the site of recreational downhill skiing, in 1946, the newly formed Aspen Skiing Company, founded by Walter Paepcke, built the first chairlift to the top of the mountain and opened the ski area that bears the name of the mountain. Nowadays, people use a gondola, which holds six people. Aspen Mountain is alternatively called Ajax by the locals

Capitol Peak (Colorado)
–
Capitol Peak is a high and prominent mountain summit in the Elk Mountains range of the Rocky Mountains of North America. Capitol Peak lies on the ridge connecting the heart of the Elk Mountains with Mount Sopris to the northwest. Capitol Peak is notable for its impressive vertical relief, rising nearly 9,000 feet above the Roaring Fork Valley, Capitol Peak is one of the most difficult of Colorados fourteeners to climb. The only non-technical route, the Northeast Ridge, requires crossing the famously exposed Knife Edge, fatalities have occurred on this route. Other routes require technical climbing, for example, the Northwest Buttress Route. These routes have significant rockfall danger due to a deal of loose rock, however.

Castle Peak is the ninth highest summit of the Rocky Mountains of North America and the U. S. state of Colorado. The prominent 14, 279-foot fourteener is the highest summit of the Elk Mountains, the summit of Castle Peak is the highest point of both counties. Castle Peak takes its name from its castellated summit, the best climbing months are June, July, August, September through the Montezuma Glacier, a permanent snowfield between Castle and Conundrum Peaks. There are two routes for ascent. The Northwest Ridge features a moderate snow climb followed by an easy ridge scramble and it should not be attempted late in the summer when the 200 feet of loose dirt and scree meet the climber near the top of the Castle-Conundrum saddle. The Northeast Ridge features an easy climb, but slightly harder scrambling and route-finding once on the ridge. Conundrum Peak is a subsummit of Castle Peak. It has two closely spaced summits, the northern is higher, with elevation of 14, 040+ feet and it is 0.4 miles north of Castle Peak, and has 200 feet of clean topographic prominence. This does not meet the usual 300-foot prominence criterion for a separate peak, however

Maroon Bells
–
The Maroon Bells are two peaks in the Elk Mountains, Maroon Peak and North Maroon Peak, separated by about a third of a mile. The mountains are on the border between Pitkin County and Gunnison County, Colorado, United States, about 12 miles southwest of Aspen, Maroon Peak, at 14,163 feet, is the 27th highest peak in Colorado. North Maroon Peak, at 14,019 feet, is the 50th highest, the view of the Maroon Bells to the southwest from the Maroon Creek valley is commonly photographed. The peaks are located in the Maroon Bells-Snowmass Wilderness of White River National Forest, a US Forest Service sign on the access trail refers to these mountains as The Deadly Bells and warns would-be climbers of downsloping, loose, rotten and unstable rock that kills without warning. Unlike other mountains in the Rockies that are composed of granite and limestone, mudstone is weak and fractures readily, giving rise to dangerously loose rock along almost any route. The mudstone is responsible for the Bells distinctive maroon color, the Bells got their deadly name in 1965 when eight people died in five separate accidents. Maroon Lake occupies a basin that was sculpted by Ice-Age glaciers and later dammed by landslide, the Maroon Bells are an increasingly popular destination for day and overnight visitors, over 300,000 people visit the Bells every season. Due to the volume of people, a bus service runs everyday from 8am-5pm from mid-June through the first weekend in October, during these times, and with just a few exceptions, personal vehicle access is limited to those with handicap placards or disability license plates. The bus runs from Aspen Highlands to Maroon Lake every 20 minutes, the Maroon Bells scenic area features several hiking trails ranging from short hikes near Maroon Lake to longer hikes into the Maroon-Snowmass Wilderness. Because the Maroon Bells area receives high levels of visitor use.

Mount Sopris
–
Mount Sopris is a twin-summit mountain in the northwestern Elk Mountains range of the Rocky Mountains of North America. Mount Sopris is located in western Pitkin County, south of Carbondale and southwest of the confluence of the Crystal, Mount Sopris is notable for having two summits, East Sopris and West Sopris, that are one-half mile apart and have the same elevation of 12,965 feet. It is named for Richard Sopris, a mayor of Denver. In 2011 J. P. McDaniels petitioned to rename East Sopris Mount John Denver after the Colorado singer, a local poll in Aspen and Carbondale said 74 percent of the respondents were against the proposal. Mount Sopris is not a volcano, but it is possible that an ancient volcano sat above it, due to subsequent continued erosion, any evidence is now gone. In either case, the rock makes up Sopris never reached the surface, cooling and crystallizing in situ. Nearby prominent peaks Mount Gunnison and Crested Butte are believed to have formed similarly, Mount Sopris dominates the skyline of Carbondale and the lower Roaring Fork Valley, serving as an unofficial symbol of the area. It is prominently visible from State Highway 82 in the vicinity of Carbondale, in terms of local relief, it is one of the largest peaks in the state of Colorado. For example, West Sopris rises 6,400 ft above the valley to the west in only 2.7 mi, in fact a vertical rise of over 6,000 feet in less than 3 miles is rare and impressive anywhere in the contiguous United States. The Mount Sopris Trail ascends to East Sopris via its east ridge and it starts near Dinkle Lake, on the northeast side of the mountain, and passes between the two Thomas Lakes just before reaching timberline. The ascent involves about 4,300 ft of vertical gain and 12 mi of hiking, it is a trail hike.

Pyramid Peak (Colorado)
–
Pyramid Peak is a fourteen thousand foot mountain in the U. S. state of Colorado. It is the 47th highest mountain peak in Colorado, and 78th highest peak in the United States and it is located in the Elk Mountains in southeastern Pitkin County, approximately 12 miles southwest of Aspen. The summit somewhat resembles a square pyramid and is visible from the Roaring Fork River valley north of Aspen along the canyon of Maroon Creek. Like many of the peaks in the Elks, Pyramid Peak is quite steep, especially compared to more gentle fourteeners such as Mount Elbert. For example, the summit rises 4,000 feet above Crater Lake to the northwest in only 1.2 miles. The standard climbing routes on Pyramid Peak are the northeast and northwest ridges and these routes involve difficult route finding, high exposure, and a great deal of loose rock. Hence they are two of the most difficult and dangerous of all of the routes on the Colorado fourteeners. List of mountain peaks of Colorado List of Colorado fourteeners Pyramid Peak

Snowmass Mountain
–
Snowmass Mountain is a fourteen thousand foot mountain in the U. S. state of Colorado and the thirty-fourth highest mountain peak in the state. Snowmass Mountain is named for the large snowfield that lies on its eastern slopes, Hagerman Peak sits between Snowmass Mountain and Snowmass Peak and is also often mistaken for Snowmass Mountain. The route most commonly used to climb Snowmass Mountain is the Snowmass Creek approach, the route to the summit starts at Snowmass Lake, which is itself an 8. 1-mile hike up Snowmass Creek from the parking area. Most people hike to the lake, camp the night and then proceed to the top and this route is recommended in the spring and early summer when the snowfield still covers much of the route, however an ice axe is recommended for travel on the snowfield. Later in the summer there is more travel on talus and more danger from rockfall, an alternative in snow-free conditions is to hike up to the saddle between the peak and Hagerman Peak. From that point there are climbers trails which proceed on the side of the ridge to the summit. A different and much less used route climbs the west side of Snowmass Mountain from Geneva Lake, Snowmass Mountain Snowmass Peak List of mountain peaks of Colorado List of Colorado fourteeners Snowmass Mountain on 14ers. com Snowmass Mountain.

Snowmass Peak in the U. S. state of Colorado dominates the view from Snowmass Lake. It is often mistaken for Snowmass Mountain, the thirty-fourth highest mountain peak in the state, Snowmass Peak is not really a peak but the lower end of Hagerman Peaks east ridge. Natural forced perspective causes the illusion that Snowmass Peak is higher than Hagerman Peak though it is actually 221 ft shorter than Hagermans summit. This illusion combined with its striking rise behind Snowmass Lake justifies it being a point on USGS topographical maps. It is located in the Elk Mountains, within the Maroon Bells-Snowmass Wilderness of the White River National Forest and it lies along the border between Pitkin and Gunnison counties, west of Aspen and southwest of the town of Snowmass Village. The route used to climb Snowmass Peak is the Trail Rider Pass trail to Hagerman Peak and this trail can be accessed by Snowmass Creek approach off Divide Road Snowmass Village or the Geneva Lake trail. It is possible to reach the summit by horse between Hagerman Peak and Snowmass Mountain, but is more difficult

Treasure Mountain (Colorado)
–
Treasure Mountain, elevation 13,535 ft, is a summit in the Elk Mountains of western Colorado. The mountain is in the Raggeds Wilderness southeast of Marble, the massif has been the site of marble mining and a legend of lost French gold. Treasure Mountain forms a massif with Treasury Mountain, elevation 13,462 feet. Another Treasure Mountain, el.11,834 feet is located in Mineral County, the Ruby Range extends southward from Treasury Mountain forming the east boundary of the Raggeds Wilderness. The Yule Lakes are a series of lakes situated on the slopes which drain into Yule Creek. The watershed is part of Crystal River basin which drains the slopes of Treasure Mountain and is the northeastern boundary of Raggeds Wilderness. Yule Pass, south of Treasury Mountain separates the Raggeds Wilderness of the Sopris Ranger District from the Gunnison Ranger District, Yule Pass is to the east of the headwaters of Yule Creek. The Colorado Yule marble comes from the Leadville Limestone of Mississippian age quarried near the mountain and it was formed by contact metamorphism in the Tertiary period following the intrusion and uplift of nearby granitic Treasure Mountain dome. Yule marble was used in the building of the Lincoln Memorial, the Yule marble quarry is at an elevation of 9,300 ft on the west side of Treasure Mountain along Yule Creek. The original name of the peak was Citadel Mountain, the current name came from an ill-fated French mining expedition described in folklore documented in the 1930s and 1940s. The folklore states that the expedition was organized in the late 1700s by Napoleon Bonaparte, the expedition was reported to have consisted of 300 men and 450 horses. They left New Orleans and traveled through Leavenworth, Kansas en route to the Rocky Mountains, the folklore claims that a large amount of gold was discovered and amassed by the expedition near Wolf Creek Pass. The local Native Americans were reportedly friendly, but relations deteriorated. In the folklore, the French buried gold and escaped the area, one survivor by the name of Le Blanc made it back to Kansas. He was the historian and was reported to have made two maps of the hidden treasure. A later expedition failed to find the treasure, william Yule, many years later, claimed to possess a copy of the original map and explored the area south and west of the mountain. The mountain was named after the legend of the missing treasure, List of mountain peaks of North America List of mountain peaks of the United States List of mountain peaks of Colorado

The Elkhead Mountains are a mountain range in Colorado. The mountain range is considered to be low altitude within Colorado as the mountains are under 11,000 feet, located within Routt and Moffat counties, the mountain range is far from metropolitan areas and has few lakes and streams, so it attracts few visitors. The mountain range is a range and all of the peaks were formed by volcanic action. Almost all of the peaks within the Elkhead Mountains are a part of Routt National Forest, significant peaks are, Bears Ears, Sugar Loaf, Saddle Mountain, Black Mountain, Pilot Knob, and Meaden Peak.

Never Summer Mountains

The Never Summer Mountains are a mountain range in the Rocky Mountains in north central Colorado in the United States consisting of seventeen named peaks. The range is small and tall, covering only 25 sq mi with a length of 10 mi while rising to over 12,000 ft at over ten distinct peaks. The range straddles the Jackson-Grand county line for most of its length, a panoramic view of the range is available from sections of Trail Ridge Road in Rocky Mountain National Park. One of the northernmost peaks, Nokhu Crags, is visible from the west side of Cameron Pass. The rocks of Never Summer Mountains are younger than most of the mountain ranges. Most of the highest peaks in the range are granodiorite that was uplifted during the Miocene epoch, the ranges highest summit, Mount Richthofen, is the remnant of an andesite volcanic plug. The Nokhu Crags in the north are mostly Pierre Shale dating from Cretaceous times, a large thrust fault underneath the Kawuneeche Valley thrust older Precambrian rocks on top of the younger Cretaceous rocks on the east side of the range. The southern peaks are Miocene-aged granite, and finally Precambrian-aged biotite gneiss, beginning two-million years ago glaciers began carving the jagged peaks of the Never Summer Mountains. Successive waves of glaciation continued to reshape the mountains until the Pinedale Glaciation ended twelve-thousand years ago, the peaks are enormous weathered masses of granitic rock heavily covered with green and orange lichens surrounded on all sides by large fields of talus shed from the original peaks. Many alpine lakes are nestled amongst the peaks, most vegetation is low-growing and stunted. Few trees grow at the altitudes and Krummholz abounds. In 1879 prospectors discovered silver on Mount Shipler, starting a small mining rush, a mining town was platted and given the name Lulu City 40°26′44″N 105°50′53″W. Other small settlements were founded in the area, including Dutchtown, the population swelled as high as 5,000 miners and business owners catering to those miners. However, low grade ore, combined with difficult transportation and lack of a smelter to process the ore conspired against the boom. By late 1883 the mining ended and the miners moved on. The last miners in Dutchtown left by 1884, today remnants of the towns and mines are accessible by hiking trails. In 1890 a project called the Grand Ditch began, the ditch is a 16.2 mi water diversion project. Streams and creeks flow from the highest peaks are diverted into the ditch

Nokhu Crags
–
Nokhu Crags is a rock formation and mountain summit in the Never Summer Mountains range of the Rocky Mountains of North America. The name is derived from the Arapaho language, Neaha-no-xhu, meaning Eagles Nest, the 12, 490-foot peak is located in State Forest State Park,2.5 miles south of Cameron Pass in Jackson County, Colorado, United States. The summit lies just northwest of the Continental Divide and Rocky Mountain National Park, the rocks of the peak were formed as a sedimentary deposit millions of years ago in an ancient ocean basin. The entire region was subsequently thrust up with the formation of the Medicine Bow Range at the close of the Mesozoic Era, around 24–29 million years ago, rising magma began to create volcanoes that were the predecessors of the Never Summer Mountains. The magma cooled into granitic formations and nearby, now vertical, after millions of years of erosion and glaciation, the vertical fin-like form of the Nohku Crags was exposed. Erosion continues to reshape the Crags, as evidenced by the talus field at its base. Today the mountain is a barren, almost treeless form, virtually devoid of vegetation, during the day, pika and mountain goats may be seen and heard on the steep slopes. In the afternoon light green and orange hues of lichen covering the face of the rocks becomes apparent, in the evening thousands of bats stream from nooks and crannies of the western face. In the winter the Nokhu Crags are covered with deep snow, an avalanche in 2013 killed a skier and buried another skier for hours
