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.

A mountain range or hill range is a series of mountains or hills ranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form and alignment that have arisen from the same cause an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are found on many planetary mass objects in the Solar System and are a feature of most terrestrial planets. Mountain ranges are segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not 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, volcanic landforms resulting in a variety of rock types. Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or the Alpide Belt.
The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera along the Pacific Coast, the Aleutian Range, on through Kamchatka, Taiwan, the Philippines, Papua New Guinea, to New Zealand. The Andes is 7,000 kilometres long and is considered the world's longest mountain system; the Alpide belt includes Indonesia and Southeast Asia, through the Himalaya, Caucasus Mountains, Balkan Mountains fold mountain range, the Alps, ends in the Spanish mountains and the Atlas Mountains. The belt includes other European and Asian mountain ranges; the Himalayas contain the highest mountains in the world, including Mount Everest, 8,848 metres high and traverses the border between China and Nepal. Mountain ranges outside these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Great Dividing Range, the Altai Mountains and the Hijaz Mountains. If the definition of a mountain range is stretched to include underwater mountains the Ocean Ridges form the longest continuous mountain system on Earth, with a length of 65,000 kilometres.
The mountain systems of the earth are characterized by a tree structure, where mountain ranges can contain sub-ranges. The sub-range relationship is 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, the White Mountains and the Blue Ridge Mountains are children of the Appalachians; the parent-child expression extends to the sub-ranges themselves: the Sandwich Range and the Presidential Range are children of the White Mountains, while the Presidential Range is parent to the Northern Presidential Range and Southern Presidential Range. The position of mountains influences climate, such as snow; when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the leeward side, it warms again and is drier, having been stripped of much of its moisture.
A rain shadow will affect the leeward side of a range. Mountain ranges are subjected to erosional forces which work to tear them down; the basins adjacent to an eroding mountain range are filled with sediments which are buried and turned into sedimentary rock. Erosion is at work while the mountains are being uplifted until the mountains are reduced to low hills and plains; the early Cenozoic uplift of the Rocky Mountains of Colorado provides an example. As the uplift was occurring some 10,000 feet of Mesozoic sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to the east; this mass of rock was removed as the range was undergoing uplift. The removal of such a mass from the core of the range most caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment.
Computer simulation has shown that as mountain belts change from tectonically active to inactive, the rate of erosion drops because there are fewer abrasive particles in the water and fewer landslides. Mountains on other planets and natural satellites of the Solar System are isolated and formed by processes such as impacts, though there are examples of mountain ranges somewhat similar to those on Earth. Saturn's moon Titan and Pluto, in particular exhibit large mountain ranges in chains composed of ices rather than rock. Examples include the Mithrim Montes and Doom Mons on Titan, Tenzing Montes and Hillary Montes on Pluto; some terrestrial planets other than Earth exhibit rocky mountain ranges, such as Maxwell Montes on Venus taller than any on Earth and Tartarus Montes on Mars, Jupiter's moon Io has mountain ranges formed from tectonic processes including Boösaule Montes, Dorian Montes, Hi'iaka Montes and Euboea Montes.

Flat Tops (Colorado)
Flat Tops is a mountain range located in Colorado within the Routt and White River National Forests. The area is home to 110 Lakes. Much of the range is within the boundary of the Flat Tops Wilderness Area; the Flat Tops Wilderness Area can be accessed by Colorado Rd 7 through the town of Yampa, in Routt County Colorado. The Flat Tops range is home to a wide variety of plants and animals, including many large mammals such as Moose, Mule deer, Black bear, Cougars; this area has been affected by Yellow toadflax.

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 south-facing 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 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 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, a band of four was spotted near the abandoned Gearhart coal mine in Mesa County, Colorado.
The Book Cliffs are one of the world's 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 foreland 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 well preserved in the Book Cliffs. Large mammals found in the Book Cliffs include coyotes, mountain lions, mule deer, black bears, 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 released in August, 2008 from a private herd on the nearby Uintah and Ouray Indian Reservation. Since this herd is located 100 miles north of the Henry Mountains, across harsh, desert terrain, it should be considered as a separate herd, the Book Cliffs bison herd.

Colorado is a state of the Western 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. It is the 8th most extensive and 21st most populous U. S. state. The estimated population of Colorado was 5,695,564 on July 1, 2018, an increase of 13.25% since the 2010 United States Census. The state was named for the Colorado River, which early Spanish explorers named the Río Colorado for the ruddy silt the river carried from the mountains; the Territory of Colorado was organized on February 28, 1861, on August 1, 1876, U. S. President Ulysses S. Grant signed Proclamation 230 admitting Colorado to the Union as the 38th state. Colorado is nicknamed the "Centennial State" because it became a state one century after the signing of the United States Declaration of Independence. Colorado is bordered by Wyoming to the north, Nebraska to the northeast, Kansas to the east, Oklahoma to the southeast, New Mexico to the south, Utah to the west, touches Arizona to the southwest at the Four Corners.
Colorado is noted for its vivid landscape of mountains, high plains, canyons, plateaus and desert lands. Colorado is part of the western and southwestern United States, is one of the Mountain States. Denver is most populous city of Colorado. Residents of the state are known as Coloradans, although the antiquated term "Coloradoan" is used. Colorado is notable for its diverse geography, which includes alpine mountains, high plains, deserts with huge sand dunes, deep canyons. In 1861, the United States Congress defined the boundaries of the new Territory of Colorado by lines of latitude and longitude, stretching from 37°N to 41°N latitude, from 102°02'48"W to 109°02'48"W longitude. After 158 years of government surveys, the borders of Colorado are now defined by 697 boundary markers and 697 straight boundary lines. Colorado and Utah are the only states that have their borders defined by straight boundary lines with no natural features; the southwest corner of Colorado is the Four Corners Monument at 36°59'56"N, 109°2'43"W.
This is the only place in the United States where four states meet: Colorado, New Mexico and Utah. The summit of Mount Elbert at 14,440 feet elevation in Lake County is the highest point in Colorado and the Rocky Mountains of North America. Colorado is the only U. S. state that lies above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County and into Cheyenne County, Kansas, is the lowest point in Colorado at 3,317 feet elevation; 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 half of Colorado is flat and rolling land. 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 3,350 to 7,500 feet; the Colorado plains are prairies but include deciduous forests and canyons. Precipitation averages 15 to 25 inches annually. Eastern Colorado is presently farmland and rangeland, along with small farming villages and towns.
Corn, hay and oats are all typical crops. Most villages and towns in this region boast both a grain elevator. Irrigation water is available from subterranean sources. Surface water sources include the South Platte, the Arkansas River, a few other streams. Subterranean water is accessed through artesian wells. Heavy use of wells for irrigation caused underground water reserves to decline. Eastern Colorado hosts considerable livestock, such as hog farms. 70% of Colorado's population resides along the eastern edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne 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, Fort Collins, Castle Rock, Colorado Springs, Pueblo and other townships and municipalities in between. On the other side of the Rockies, the significant population centers in Western Colorado are the cities of Grand Junction and Montrose.
The Continental Divide of the Americas extends along the crest of the Rocky Mountains. The area of Colorado to the west of the Continental Divide is called the Western Slope of Colorado. West of the Continental Divide, water flows to the southwest via the Colorado River and the Green River into the Gulf of California. Within the interior of the Rocky Mountains are several large parks which are high broad basins. In the north, on the east side of the Continental Divide is the North Park of Colorado; the North Park is drained by the North Platte River, which flows north into Nebraska. Just to the south of North Park, but on the western side of the Continental Divide, is the Middle Park of Colorado, drained by the Colorado River; the South Park of Colorado is the region of the headwaters of the South Platte River. In southmost Colorado is the large San Luis Valley, where the headwaters of the Rio Grande are located; the valley sits between the Sangre De Cristo Mountains and San Juan Mountains, consists of large desert lands that run into the mountains.
The Rio Grande drains due south into New Mexico and Texas. Across the Sangre de Cristo Range to the east of the S
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.
