Castle Peak (Colorado)
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 and the Maroon Bells-Snowmass Wilderness; the peak is located 11.6 miles northeast by north of the Town of Crested Butte, United States, on the drainage divide separating Gunnison National Forest and Gunnison County from White River National Forest and Pitkin County. 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, August, September through the Montezuma Glacier, a permanent snowfield between Castle and Conundrum Peaks. There are two standard routes for ascent; the Northwest Ridge features a moderate snow climb followed by an easy ridge scramble. 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 snow climb, but harder scrambling and route-finding once on the ridge.
There are two other peaks in Colorado that have the same name: one in Eagle County at 39°46′23″N 106°50′04″W, with an elevation 11,280+ feet,. Conundrum Peak is a northern subsummit of Castle Peak, it has two spaced summits. It is 0.4 miles north of Castle Peak, has 200 feet of clean topographic prominence. This does not meet the usual 300-foot prominence criterion for an separate peak.

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.

Aspen Mountain (Colorado)
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, United States. The north face of the mountain is the location of the Aspen Mountain ski area, one of four adjacent ski areas operated collectively as Aspen/Snowmass. Aspen Mountain is not high, relative to other mountains in Colorado, but nonetheless looms over the town of Aspen because of the proximity of the town, founded as a silver mining camp in 1879 during the Colorado Silver Boom; 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 modern gondola, to get to the top of the mountain. Aspen Mountain is alternatively called Ajax by the locals.

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
Jet is a type of lignite, a precursor to coal, is a gemstone. Jet is not a mineral, but rather a mineraloid, it has an organic origin, being derived from wood. The English noun "jet" derives from the French word for the same material, jaiet referring to the ancient town of Gagae. Jet is either black or dark brown, but may contain pyrite inclusions, which are of brassy colour and metallic lustre; the adjective "jet-black", meaning as dark a black as possible, derives from this material. Jet is a product of high-pressure decomposition of wood from millions of years ago the wood of trees of the family Araucariaceae. Jet is found in two forms and soft. Hard jet is the result of salt water; the jet found at Whitby, in England, is of early Jurassic age 182 million years old. Whitby Jet is the fossilized wood from species similar to the extant Chile pine or Monkey Puzzle tree. Jet is found in Poland and Santiago de Compostela in northern Spain and near Erzurum in Turkey, where it is used to make prayer beads.
Native American Navajo and Pueblo tribes of New Mexico were using regionally mined jet for jewellery and the ornamentation of weapons when early Spanish explorers reached the area in the 1500s. Today these jet deposits are known for the Acoma Pueblo. Enormous coal deposits characterize the San Juan Basin of New Mexico and this geology is related to jet deposits mined in the Henry Mountains of Utah and the Front Range of El Paso County, Colorado. Jet has been used in Britain since the Neolithic period, but the earliest known object is a 10,000 BC model of a botfly larva, from Baden-Württemberg, found among the Venuses of Petersfels, it continued in use in Britain through the Bronze Age. During the Iron Age jet went out of fashion until the early-3rd century AD in Roman Britain; the end of Roman Britain marked the end of jet's ancient popularity, despite sporadic use in the Anglo-Saxon and Viking periods and the Medieval period. Jet regained popularity with a massive resurgence during the Victorian era.
Whitby jet was a popular material for jewellery in Roman Britain from the 3rd century onward. It was used in rings, hair pins, bracelets, bangles and pendants, many of which are visible in the Yorkshire Museum. There is no evidence for Roman jet working in Whitby itself, rather it was transferred to Eboracum where considerable evidence for jet production has been found; the collection of jet at this time was based on beachcombing rather than quarrying. In the Roman period it saw use as a magical material used in amulets and pendants because of its supposed protective qualities and ability to deflect the gaze of the evil eye. Pliny the Elder suggests that "the kindling of jet drives off snakes and relieves suffocation of the uterus, its fumes detect attempts to simulate a disabling illness or a state of virginity." It has been referenced by other ancient writers including Galen. Jet objects were exported from Eboracum all into Europe. Around the Rhine some jet bracelets from the period have been found that feature grooves with gold inserts.
Jet as a gemstone was fashionable during the reign of Queen Victoria, during which the Queen wore Whitby jet as part of her mourning dress, mourning the death of Prince Albert. Jet was associated with mourning jewellery in the 19th century because of its sombre colour and modest appearance, it has been traditionally fashioned into rosaries for monks. In some jewellery designs of the period jet was combined with cut steel. In the United States, long necklaces of jet beads were popular during the Roaring Twenties, when women and young flappers would wear multiple strands of jet beads stretching from the neckline to the waistline. In these necklaces, the jet was strung using heavy cotton thread. Jet has been known as black amber, as it may induce an electric charge like that of amber when rubbed. Jet is easy to carve, but it is difficult to create fine details without breaking so it takes an experienced lapidary to execute more elaborate carvings. Jet has a Mohs hardness ranging between 2.5 and 4 and a specific gravity of 1.30 to 1.34.
The refractive index of jet is 1.66. The touch of a red-hot needle should cause jet to emit an odour similar to coal. Although now much less popular than in the past, authentic jet jewels are valued by collectors. Unlike black glass, cool to the touch, jet is not cool, due to its lower thermal conductivity. Glass was used as a jet substitute during the peak of jet's popularity; when it was used in this way it was known as French Vauxhall glass. Ebonite was used as a jet substitute and looks similar to jet, but it fades over time. In some cases jet offcuts were molded into jewellery. Anthracite is superficially similar to fine jet, has been used to imitate it; this imitation is not always easy to distinguish from real jet. When rubbed against unglazed porcelain, true jet will leave a chocolate brown streak; the microstructure of jet, which resembles the original wood, can be seen under 120× or greater magnification.

The Rocky Mountains known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than 4,800 kilometers from the northernmost part of British Columbia, in western Canada, to New Mexico in the Southwestern United States. Located within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges, Cascade Range, the Sierra Nevada, which all lie farther to the west; the Rocky Mountains formed 80 million to 55 million years ago during the Laramide orogeny, in which a number of plates began sliding underneath the North American plate. The angle of subduction was shallow, resulting in a broad belt of mountains running down western North America. Since further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks and valleys. At the end of the last ice age, humans began inhabiting the mountain range. After Europeans, such as Sir Alexander Mackenzie, Americans, such as the Lewis and Clark expedition, began exploring the range and furs drove the initial economic exploitation of the mountains, although the range itself never experienced dense population.
Public parks and forest lands protect much of the mountain range, they are popular tourist destinations for hiking, mountaineering, hunting, mountain biking and snowboarding. The name of the mountains is a translation of an Amerindian name, related to Algonquian; the first mention of their present name by a European was in the journal of Jacques Legardeur de Saint-Pierre in 1752, where they were called "Montagnes de Roche". The Rocky Mountains are defined as stretching from the Liard River in British Columbia south to the Rio Grande in New Mexico; the Rockies vary in width from 110 to 480 kilometres. The Rocky Mountains are notable for containing the highest peaks in central North America; the range's highest peak is Mount Elbert located in Colorado at 4,401 metres above sea level. Mount Robson in British Columbia, at 3,954 metres, is the highest peak in the Canadian Rockies; the eastern edge of the Rockies rises above the Interior Plains of central North America, including the Sangre de Cristo Mountains of New Mexico and Colorado, the Front Range of Colorado, the Wind River Range and Big Horn Mountains of Wyoming, the Absaroka-Beartooth ranges and Rocky Mountain Front of Montana and the Clark Range of Alberta.
The western edge of the Rockies includes ranges such as the Wasatch near Salt Lake City and the Bitterroots along the Idaho-Montana border. The Great Basin and Columbia River Plateau separate these subranges from distinct ranges further to the west. In Canada, the western edge of the Rockies is formed by the huge Rocky Mountain Trench, which runs the length of British Columbia from its beginnings in the middle Flathead River valley in western Montana to the south bank of the Liard River. Geographers define three main groups of the Canadian Rockies: the Continental Ranges, Hart Ranges, Muskwa Ranges; the Rockies do not extend into central British Columbia. Other mountain ranges continue beyond the Liard River, including the Selwyn Mountains in Yukon, the Brooks Range in Alaska, but those are not part of the Rockies, though they are part of the American Cordillera; the Continental Divide of the Americas is located in the Rocky Mountains and designates the line at which waters flow either to the Atlantic or Pacific Oceans.
Triple Divide Peak in Glacier National Park is so named because water falling 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, which has its outlet on the Beaufort Sea of the Arctic Ocean. Human population is not dense in the Rocky Mountains, with an average of four people per square kilometer and few cities with over 50,000 people. However, the human population grew in the Rocky Mountain states between 1950 and 1990; the forty-year statewide increases in population range from 35% in Montana to about 150% in Utah and Colorado. The populations of several mountain towns and communities have doubled in the last forty years. Jackson, increased 260%, from 1,244 to 4,472 residents, in forty years; the rocks in the Rocky Mountains were formed. The oldest rock is Precambrian metamorphic rock. There is Precambrian sedimentary argillite, dating back to 1.7 billion years ago. During the Paleozoic, western North America lay underneath a shallow sea, which deposited many kilometers of limestone and dolomite.
In the southern Rocky Mountains, near present-day Colorado, these ancestral rocks were disturbed by mountain building 300 Ma, during the Pennsylvanian. This mountain-building produced the Ancestral Rocky Mountains, they consisted of Precambrian metamorphic rock forced upward through layers of the limestone laid down in the shallow sea. The mountains eroded throughout the late Paleozoic and early Mesozoic, leaving extensive deposits of sedimentary rock. Terranes began colliding with the western edge of North America in the Mississippian, causing the Antler orogeny. For 270 million years, the focus of the effects of plate collisions were near the edge of the North American plate boundary, far to the west of the Rocky Mountain region, it was. The current Rocky Mountains arose in the Laramide orogeny from between 55 Ma. For the Canadi
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.
