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 mountains sit on the western side of the Continental Divide in southern Pitkin and northern Gunnison counties, in the area southwest of Aspen, south of the Roaring Fork River valley, east of the Crystal River; the range sits 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, North Maroon Peak. Maroon Peak and North Maroon Peak are collectively known as the Maroon Bells, a popular destination for recreation alpinism. 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, serving as an unofficial symbol of the area.
Additional notable peaks in the range include: Cathedral Peak, 13,943 ft, near Pyramid Peak Hagerman Peak, 13,841 ft, near Snowmass Mountain Snowmass Peak, 13,620 ft, near Hagerman Peak Clark Peak, 13,580 ft, near Capitol Peak Treasure Mountain, 13,528 ft, southwest of the Maroon Bells Mount Owen, 13,058 ft, high point of the Ruby Range Mount Sopris, 12,965 ft, north west of Capitol Peak Chair Mountain, 12,721 ft, high point of The Raggeds Crested Butte, 12,162 ft, home of Crested Butte Mountain Resort Whitehouse Mountain, 11,975 ft, northwest of Treasure MountainThe range provides a formidable barrier to travel and is traversed only by backroad passes and trails, including Schofield Pass, Pearl Pass, Taylor Pass. State Highway 133 traverses McClure Pass, at the western end of the range; the range has been the site of mining activity since the days of the Colorado Silver Boom, which saw the founding of mining towns such as Aspen and Ashcroft. 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 the westerly origin of many winter storms. 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. West Elk Mountains "Rocky Mountains".

Elk Mountain (Routt County, Colorado)
Elk Mountain is a summit in Routt County, Colorado. The mountain lies to the northwest of Steamboat Springs and is seen from the city from along Lincoln Avenue, Steamboat's main street; the mountain is easily seen from Mount Werner, the home of the Steamboat Ski Resort. The Elk River flows near the mountain just before its confluence with the Yampa River in the Yampa Valley. Locals refer to the mountain as "The Sleeping Giant," due to its resemblance to the profile of a prone person at sleep when viewed from Mount Werner or Steamboat Springs, have created legends to explain this appearance. There are at least six other summits named Elk Mountain in Colorado; this Elk Mountain in Routt County is not part of the Elk Mountains in West Central Colorado. Instead, it is one of the easternmost peaks in the Elkhead Mountains
Mount Sopris is a twin-summit mountain in the northwestern Elk Mountains range of the Rocky Mountains of North America. The 12,965-foot mountain is located in the Maroon Bells-Snowmass Wilderness of White River National Forest, 6.6 miles north by northeast of the community of Redstone in Pitkin County, United States. Mount Sopris is located in western Pitkin County, south of Carbondale and southwest of the confluence of the Crystal and Roaring Fork rivers. 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 former mayor of Denver and part of the first European expedition in the Roaring Fork Valley. 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. Mount Sopris is believed to have been formed by an igneous intrusion 10,000 feet below the earth's surface, geologically referred to as a pluton, that occurred around 30 million years ago, after the initial uplift of the modern Rocky Mountains.
Mount Sopris is not a volcano, but it is possible that an ancient volcano sat above it, with the current rock forming the magma chamber far below. Due to subsequent continued erosion, any evidence is now gone. In either case, the rock that makes up Sopris never reached the surface and crystallizing in situ, becoming exposed due to erosion. 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. It starts near Dinkle Lake, on the northeast side of the mountain, passes between the two Thomas Lakes just before reaching timberline.
The ascent involves 12 mi of hiking.

United States Geological Survey
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 natural resources, the natural hazards that threaten it; the organization has four major science disciplines, concerning biology, geography and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility; the USGS is a bureau of the United States Department of the Interior. The USGS employs 8,670 people and is headquartered in Reston, Virginia; the USGS has major offices near Lakewood, Colorado, at the Denver Federal Center, Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world." The agency's previous slogan, adopted on the occasion of its hundredth anniversary, was "Earth Science in the Public Service." Since 2012, the USGS science focus is directed at six topical "Mission Areas", namely Climate and Land Use Change, Core Science Systems, Ecosystems and Minerals and Environmental Health, Natural Hazards, Water.
In December 2012, the USGS split the Energy and Minerals and Environmental Health Mission Area resulting in seven topical Mission Areas, with the two new areas being: Energy and Minerals and Environmental Health. Administratively, it is divided into 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 and magnitude of global earthquakes. The USGS 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, the public, both domestic and worldwide, about significant earthquakes. It maintains long-term archives of earthquake data for scientific and engineering research, it conducts and supports research on long-term seismic hazards. USGS has released the UCERF California earthquake forecast.
As of 2005, the agency is working to create a National Volcano Early Warning System by improving the instrumentation monitoring the 169 volcanoes in U. S. territory and by establishing methods for measuring the relative threats posed at each site. The USGS National Geomagnetism Program monitors the magnetic field at magnetic observatories and distributes magnetometer data in real time; the USGS collaborates with Canadian and Mexican government scientists, along with the Commission for Environmental Cooperation, to produce the North American Environmental Atlas, used to depict and track environmental issues for a continental perspective. The USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data are available online. National Climate Change and Wildlife Science Center implements partner-driven science to improve understanding of past and present land use change, develops relevant climate and land use forecasts, identifies lands and communities that are most vulnerable to adverse impacts of change from the local to global scale.
Since 1962, the Astrogeology Research Program has been involved in global and planetary exploration and mapping. In collaboration with Stanford University, the USGS operates the USGS-Stanford Ion Microprobe Laboratory, a world-class analytical facility for U--Pb geochronology and trace element analyses of minerals and other earth materials. USGS operates a number of water related programs, notably the National Streamflow Information Program and National Water-Quality Assessment Program. USGS Water data is publicly available from their National Water Information System database; the USGS operates the National Wildlife Health Center, whose mission is "to serve the nation and its natural resources by providing sound science and technical support, to disseminate information to promote science-based decisions affecting wildlife and ecosystem health. The NWHC provides information, technical assistance, research and leadership on national and international wildlife health issues." It is the agency responsible for surveillance of H5N1 avian influenza outbreaks in the United States.
The USGS runs 17 biological research centers in the United States, including the Patuxent Wildlife Research Center. The USGS is investigating collaboration with the social networking site Twitter to allow for more rapid construction of ShakeMaps; the USGS produces several national series of topographic maps which vary in scale and extent, with some wide gaps in coverage, notably the complete absence of 1:50,000 scale topographic maps or their equivalent. The largest and best-known topographic series is the 7.5-minute, 1:24,000 scale, quadrangle, a non-metric scale unique to the United States. Each of these maps covers an area bounded by two lines of latitude and two lines of longitude spaced 7.5 minutes apart. Nearly 57,000 individual maps in this series cover the 48 contiguous states, Hawaii, U. S. territories, areas of Alaska near Anchorage and Prudhoe Bay. The area covered by each map varies with the latitude of its represented location due to convergence of the meridians. At lower latitudes, near 30° north, a 7.5-minute quadrangle contains an area of about 64 square miles.
At 49° north latitude, 49 square miles are contained within a quadrangle of that size. As a unique non-metric map scale, the 1:24,000 scale requires a separate and specialized romer scale for pl
Snowmass Mountain is a fourteen thousand foot tall mountain in the U. S. state of Colorado, is the thirty-fourth highest mountain peak in the state. Located in the Elk Mountains, within the Maroon Bells-Snowmass Wilderness of the White River National Forest, it lies along the border between the Pitkin and Gunnison counties, west of Aspen and southwest of the town of Snowmass Village. Snowmass Mountain is named for the large snowfield. Snowmass Mountain should not be confused with the Snowmass ski area, located outside Snowmass Village. Hagerman Peak sits between Snowmass Mountain and Snowmass Peak and is often mistaken for Snowmass Mountain; the route most used to climb Snowmass Mountain is the Snowmass Creek approach. The route to the summit starts at Snowmass Lake, itself an 8.1-mile hike up Snowmass Creek from the parking area. Most people hike to the lake, camp the night and proceed to the top; this route is recommended in the spring and early summer when the snowfield still covers much of the route.
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 opposite side of the ridge to the summit. A different and much less used route climbs the west side of Snowmass Mountain from Geneva Lake, accessed from the North Fork of the Crystal River.

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 volcanic range and all of the peaks were formed by volcanic action. The mountain range extends 16 miles east to west and 10 miles north to south, its center is located at 40.77404°N 107.32132°W / 40.77404. 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, Meaden Peak.

A mountain is a large landform that rises above the surrounding land in a limited area in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism; these forces can locally raise the surface of the earth. Mountains erode through the action of rivers, weather conditions, glaciers. A few mountains are isolated summits. High elevations on mountains produce colder climates than at sea level; these colder climates 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, such as mountain climbing; 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, relief, steepness and continuity have been used as criteria for defining a mountain. In the Oxford English Dictionary a mountain is defined as "a natural elevation of the earth surface rising more or less abruptly from the surrounding level and attaining an altitude which to the adjacent elevation, is impressive or notable."Whether a landform is called a mountain may depend on local usage. Mount Scott outside Lawton, Oklahoma, USA, is only 251 m from its base to its highest point. Whittow's Dictionary of Physical Geography states "Some authorities regard eminences above 600 metres as mountains, those below being referred to as hills." In the United Kingdom and the Republic of Ireland, a mountain is defined as any summit at least 2,000 feet high, whilst the official UK government's definition of a mountain, for the purposes of access, is a summit of 600 metres or higher. In addition, some definitions include a topographical prominence requirement 100 or 500 feet. At one time the U.
S. Board on Geographic Names defined a mountain as being 1,000 feet or taller, but has abandoned the definition since the 1970s. Any similar landform lower. However, the United States Geological Survey concludes that these terms do not have technical definitions in the US; the UN Environmental Programme's definition of "mountainous environment" includes any of the following: Elevation of at least 2,500 m. Using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, 14% of Africa; as a whole, 24% of the Earth's land mass is mountainous. There are three main types of mountains: volcanic and block. All three types are formed from plate tectonics: when portions of the Earth's crust move and dive. 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 steeper, a mountain. Major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity.
Volcanoes are formed when a plate is pushed at a mid-ocean ridge or hotspot. At a depth of around 100 km, melting occurs in rock above the slab, forms magma that reaches the surface; when the magma reaches the surface, it builds a volcanic mountain, such as a shield volcano or a stratovolcano. Examples of volcanoes include 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. Fold mountains occur when two plates collide: shortening occurs along thrust faults and the crust is overthickened. Since the less dense continental crust "floats" on the denser mantle rocks beneath, the weight of any crustal material forced upward to form hills, plateaus or mountains must be balanced by the buoyancy force of a much greater volume forced downward into the mantle, thus the continental crust is much thicker under mountains, compared to lower lying areas.
Rock can fold either asymmetrically. The upfolds are anticlines and the downfolds are synclines: in asymmetric folding there may be recumbent and overturned folds; the Balkan Mountains and the Jura Mountains are examples of fold mountains. Block mountains are caused by faults in the crust: a plane; when rocks on one side of a fault rise relative to the other, it can form a mountain. The uplifted blocks are block horsts; the intervening dropped blocks are termed graben: these can be small or form extensive rift valley systems. This form of landscape can be seen in East Africa, the Vosges, the Basin and Range Province of Western North America and the Rhine valley; these areas occur when the regional stress is extensional and the crust is thinned. During and following uplift, mountains are subjected to the agents of erosion which wear the uplifted area down. Erosion causes the surface of mountains to be younger than the rocks that form the mountains themselves. Glacial processes produce characteristic landforms, such as pyramidal peaks, knife-edge arêtes, bowl-shaped cirques that can contai
