Capitol Peak (Colorado)
Capitol Peak is a high and prominent mountain summit in the Elk Mountains range of the Rocky Mountains of North America. The 14,137-foot fourteener is located in the Maroon Bells-Snowmass Wilderness of White River National Forest, 8.7 miles east by south of the community of Redstone in Pitkin County, United States. Capitol Peak lies on the long 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 Colorado's fourteeners to climb; the only non-technical route, the Northeast Ridge, requires crossing the famously exposed "Knife Edge," the northeast ridge of Capitol. Fatalities have occurred on this route. Other routes require technical rock climbing, for the Northwest Buttress Route; these routes have significant rockfall danger due to a great deal of loose rock.

The Front Range is a mountain range of the Southern Rocky Mountains of North America located in the central portion of the U. S. State of Colorado, southeastern portion of the U. S. State of Wyoming, it is the first mountain range encountered as one goes westbound along the 40th parallel north across the Great Plains of North America. The Front Range runs north-south between Casper and Pueblo, Colorado and rises nearly 10,000 feet above the Great Plains. Longs Peak, Mount Evans, Pikes Peak are its most prominent peaks, visible from the Interstate 25 corridor; the area is a popular destination for mountain biking, hiking and camping during the warmer months and for skiing and snowboarding during winter. Millions of years ago, the present-day Front Range was home to ancient mountain ranges, deserts and oceans; the name "Front Range" is applied to the Front Range Urban Corridor, the populated region of Colorado and Wyoming just east of the mountain range and extending from Cheyenne, Wyoming south to Pueblo, Colorado.
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 molten rock that would one day amalgamate, drift together and combine, to form the continents we live on today. In the Colorado region, this molten rock spewed and cooled, forming what we now know as the Precambrian Pikes Peak Granite. 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 and sediments began to deposit in the newly formed accommodation space. Eroded granite produced sand particles that began to form strata, layers of sediment, in the sinking basin. Sedimentation would continue to take place until about 300 million years ago. Around 300 million years ago, the sinking reversed, the sediment-covered granite began to uplift, giving rise to the Ancestral Rocky Mountains.
Over the next 150 million years, during uplift the mountains would continue to erode and cover themselves in their own sediment. Wind, rainwater and ice-melt supplied rivers that carved through the granite mountains and led to their end; the sediment from these mountains lies in the Fountain Formation today. Red Rocks Amphitheatre 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 and leaf imprints in many of the strata making up the section. 30 million years the sediment deposition was still taking place with the introduction of the Lykins Formation. This formation can be best attributed to its wavy layers of muddy limestone and signs of stromatolites that thrived in a smelly tidal flat at present-day Colorado.
250 million years ago, the Ancestral Rockies were burying themselves while the shoreline was present during the break-up of Pangaea. This formation began right after Earth's largest extinction 251 million years ago at the Permian–Triassic Boundary. Ninety percent of the planet's marine life was a great deal on land as well. After 100 million years of deposition, a new environment brought rise to a new formation, the sandstone Morrison Formation; the Morrison Formation contains some of the best fossils of the Late Jurassic. It is known for its sauropod tracks and sauropod bones among other dinosaur fossils; as identified by the fossil record, the environment was filled with various types of vegetation such as ferns and Zamites. While this time period boasts many types of plants, grass had not yet evolved; the Dakota Sandstone, deposited 100 million years ago towards Colorado's eastern coast, shows evidence of ferns, dinosaur tracks. Sheets of ripple marks can be seen on some of the strata. Over the next 30 million years, the region was taken over by a deep sea, the Cretaceous Western Interior Seaway, deposited mass amounts of shale over the area known as the Pierre Shale.
Both the thick section of shale and the marine life fossils found. Colorado drained from being at the bottom of an ocean to land again, giving yield to another fossiliferous rock layer, the Denver Formation. At about 68 million years ago, the Front Range began to rise again due to the Laramide Orogeny in the west; the Denver Formation contained fossils and bones from dinosaurs like Tyrannosaurus rex and Triceratops. While the forests of vegetation and other organisms thrived, their reign would come to an end at the Cretaceous–Paleogene boundary. In an instant, millions of species are obliterated from a meteor impact in Mexico's Yucatán Peninsula. While this extinction led to the demise of the dinosaurs and other organisms, some life did prevail to repopulate the earth as it recovered from this tremendous disaster; the uplifted Front Range continued to erode and, by 40 million years ago, the range was once again buried in its own rubble. 37 million years ago, a great volcanic eruption took place in the Collegiate Range and covered the landscape in molten hot ash that torched and consumed everything across the landscape.
An entire lush environment was capped in a matter of minutes with 20 feet of extr
Snowmass Peak in the U. S. state of Colorado dominates the view from Snowmass Lake. It is mistaken for Snowmass Mountain, the thirty-fourth highest mountain peak in the state, as well as for Hagerman Peak. Snowmass Peak is not a peak but the lower end of Hagerman Peak's east ridge. Natural forced perspective causes the optical illusion that Snowmass Peak is higher than Hagerman Peak though it is 221 ft shorter than Hagerman's summit; this illusion combined with its striking rise behind Snowmass Lake justifies it being a named point on USGS topographical maps. It is located in the Elk Mountains, within the Maroon Bells-Snowmass Wilderness of the White River National Forest, 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; 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 between Hagerman Peak and Snowmass Mountain, but is much more difficult.

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
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, 78th highest peak in the United States, it is located in the Elk Mountains in southeastern Pitkin County 12 miles southwest of Aspen. The summit somewhat resembles a ragged 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 compared to more gentle fourteeners such as Mount Elbert. For example, the peak's summit rises 4,000 feet above Crater Lake to the northwest in only 1.2 miles, 4,400 feet above East Maroon Creek to the east of the peak in the same horizontal distance. The standard climbing routes on Pyramid Peak are the northwest ridges; these routes involve difficult route finding, high exposure, a great deal of loose rock. Hence they are two of the most difficult and dangerous of all of the standard routes on the Colorado fourteeners. List of mountain peaks of Colorado List of Colorado fourteeners "Pyramid Peak".

U.S. National Geodetic Survey
"United States Coast Survey" and "United States Coast and Geodetic Survey" redirect here. They are former scientific agencies of the United States government which should not be confused with the United States Coast Guard, a seagoing U. S. government law enforcement and safety agency, the modern Coast Survey, a U. S. government agency that makes nautical charts, or the United States Geological Survey, a U. S. government agency that studies earth science and makes topographical maps. The National Geodetic Survey the United States Survey of the Coast, United States Coast Survey, United States Coast and Geodetic Survey, is a United States federal agency that defines and manages a national coordinate system, providing the foundation for transportation and communication. Since its foundation in its present form in 1970, it has been part of the National Oceanic and Atmospheric Administration, of the United States Department of Commerce; the National Geodetic Survey's history and heritage are intertwined with those of other NOAA offices.
As the U. S. Coast Survey and U. S. Coast and Geodetic Survey, the agency operated a fleet of survey ships, from 1917 the Coast and Geodetic Survey was one of the uniformed services of the United States with its own corps of commissioned officers. Upon the creation of the Environmental Science Services Administration in 1965, the commissioned corps was separated from the Survey to become the Environmental Science Services Administration Corps. Upon the creation of NOAA in 1970, the ESSA Corps became the National Oceanic and Atmospheric Administration Commissioned Officer Corps. Thus, the National Geodetic Survey's ancestor organizations are the ancestors of today's NOAA Corps and Office of Coast Survey and are among the ancestors of today's NOAA fleet. In addition, today's National Institute of Standards and Technology, although long since separated from the Survey, got its start as the Survey's Office of Weights and Measures; the National Geodetic Survey is an office of NOAA's National Ocean Service.
Its core function is to maintain the National Spatial Reference System, "a consistent coordinate system that defines latitude, height, scale and orientation throughout the United States." NGS is responsible for defining the NSRS and its relationship with the International Terrestrial Reference Frame. The NSRS enables precise and accessible knowledge of where things are in the United States and its territories; the NSRS may be divided into its geometric and physical components. The official geodetic datum of the United States, NAD83 defines the geometric relationship between points within the United States in three-dimensional space; the datum may be accessed via NGS's network of survey marks or through the Continuously Operating Reference Station network of GPS reference antennas. NGS is responsible for computing the relationship between NAD83 and the ITRF; the physical components of the NSRS are reflected in its height system, defined by the vertical datum NAVD88. This datum is a network of orthometric heights obtained through spirit leveling.
Because of the close relationship between height and Earth's gravity field, NGS collects and curates terrestrial gravity measurements and develops regional models of the geoid and its slope, the deflection of the vertical. NGS is responsible for ensuring the accuracy of the NSRS over time as the North American plate rotates and deforms over time due to crustal strain, post-glacial rebound, elastic deformation of the crust, other geophysical phenomena. NGS will release new datums in 2022; the North American Terrestrial Reference Frame of 2022 will supersede NAD83 in defining the geometric relationship between the North American plate and the ITRF. United States territories on the Pacific and Mariana plates will have their own respective geodetic datums; the North American-Pacific Geopotential Datum of 2022 will separately define the height system of the United States and its territories, replacing NAVD88. It will use a geoid model accurate to 1 centimeter to relate orthometric height to ellipsoidal height measured by GPS, eliminating the need for future leveling projects.
This geoid model will be based on airborne and terrestrial gravity measurements collected by NGS's GRAV-D program as well as satellite-based gravity models derived from observations collected by GRACE, GOCE, satellite altimetry missions. NGS provides a number of other public services, it maps changing shorelines in the United States and provides aerial imagery of regions affected by natural disasters, enabling rapid damage assessment by emergency managers and members of the public. The Online Positioning and User Service processes user-input GPS data and outputs position solutions within the NSRS; the agency offers other tools for conversion between datums. The original predecessor agency of the National Geodetic Survey was the United States Survey of the Coast, created within the United States Department of the Treasury by an Act of Congress on February 10, 1807, to conduct a "Survey of the Coast." The Survey of the Coast, the United States government's first scientific agency, represented the interest of the administration of President Thomas Jefferson in science and the stimulation of international trade by using scientific surveying methods to chart t
San Juan Mountains
The San Juan Mountains are a high and rugged mountain range in the Rocky Mountains in southwestern Colorado and northwestern New Mexico. The area is mineralized and figured in the gold and silver mining industry of early Colorado. Major towns, all old mining camps, include Creede, Lake City, Silverton and Telluride. Large scale mining has ended in the region, although independent prospectors still work claims throughout the range; the last large scale mines were the Sunnyside Mine near Silverton, which operated until late in the 20th century and the Idarado Mine on Red Mountain Pass that closed down in the 1970s. Famous old San Juan mines include the Camp Bird and Smuggler Union mines, both located between Telluride and Ouray; the Summitville mine was the scene of a major environmental disaster in the 1990s when the liner of a cyanide-laced tailing pond began leaking heavily. Summitville is in the Summitville caldera, one of many extinct volcanoes making up the San Juan volcanic field. One, La Garita Caldera, is 35 miles in diameter.
Large beds of lava, some extending under the floor of the San Luis Valley, are characteristic of the eastern slope of the San Juans. Tourism is now a major part of the regional economy, with the narrow gauge railway between Durango and Silverton being an attraction in the summer. Jeeping is popular on the old trails which linked the historic mining camps, including the notorious Black Bear Road. Visiting old ghost towns is popular, as is wilderness trekking and mountain climbing. Many of the old mining camps are now popular sites of summer homes. Though the San Juans are steep and receive a lot of snow, so far only Telluride has made the transition to a major ski resort. Purgatory Resort, once known as Durango Mountain Resort, is a small ski area 26 miles north of Durango. There is skiing on Wolf Creek Pass at the Wolf Creek ski area. Silverton Mountain ski area has begun operation near Silverton; the Rio Grande drains the east side of the range. The other side of the San Juans, the western slope of the continental divide, is drained by tributaries of the San Juan and Gunnison rivers, which all flow into the Colorado River.
The San Juan and Uncompahgre National Forests cover a large portion of the San Juan Mountains. The San Juan Mountains are distinctive for their high altitude plateaus and peaks; as a result, facilities in the towns and cities of the region are among the highest in the nation. Telluride Airport, at an elevation of 9,070 feet, is the highest in the United States with scheduled commercial service. Note: This is only a partial list of important peaks in the San Juans, listing peaks by prominence only. There are dozens more summits over 12,000 feet. Mining operators in the San Juan mountain area formed the San Juan District Mining Association in 1903, as a direct result of a Western Federation of Miners proposal to the Telluride Mining Association for the eight-hour day, approved in a referendum by 72 percent of Colorado voters; the new association consolidated the power of thirty-six mining properties in San Miguel and San Juan counties. The SJDMA refused to consider any reduction in hours or increase in wages, helping to provoke a bitter strike.
