White River Plateau
The White River Plateau is a "broad structural dome" located north of Glenwood Springs, Colorado and north of the Colorado River. Also called the White River Uplift, the mountainous area is shown on maps as being roughly circular in area, occupying parts of the Colorado counties of Garfield and Rio Blanco, with small portions extending into Eagle and Routt counties. The Grand Hogback marks parts of the plateau's southern and western boundaries. The Flat Tops mountain range is part of the White River Plateau, and much of the plateau is located within the White River National Forest. The summit of Blair Mountain, elevation , is the plateau's highest point. Geology The plateau forms part of the Southern Rocky Mountains. It was created during the Eocene, during the latter part of the Laramide orogeny The Laramide orogeny was a time period of mountain building in western North America, which started in the Late Cretaceous, 70 to 80 million years ago, and ended 35 to 55 million y ...

Dome (geology)
A dome is a feature in structural geology consisting of symmetrical anticlines that intersect each other at their respective apices. Intact, domes are distinct, rounded, spherical-to- ellipsoidal-shaped protrusions on the Earth's surface. However, a transect parallel to Earth's surface of a dome features concentric rings of strata. Consequently, if the top of a dome has been eroded flat, the resulting structure in plan view appears as a bullseye, with the youngest rock layers at the outside, and each ring growing progressively older moving inwards. These strata would have been horizontal at the time of deposition, then later deformed by the uplift associated with dome formation. Formation mechanisms There are many possible mechanisms responsible for the formation of domes, the foremost of which are post-impact uplift, refolding, and diapirism. Post-impact uplift A complex crater, caused by collision of a hypervelocity body with another larger than itself, is typified by th ...

Mountain Ranges Of Colorado
This is a list of the major mountain ranges in the U.S. State of Colorado. All of these ranges are considered subranges of the Southern Rocky Mountains. As given in the table, topographic elevation is the vertical distance above the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface. The topographic prominence of a summit is the elevation difference between that summit and the highest or key col to a higher summit. The topographic isolation of a summit is the minimum great-circle distance to a point of equal elevation. All elevations in this article include an elevation adjustment from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88). For further information, please see this United States National Geodetic Surveybr>note If an elevation or prominence is calculated as a range of values, the arithmetic mean is shown. __TOC__ Mountain ranges Gallery Image:Mo ...

Plateaus Of The United States
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laramide Orogeny
The Laramide orogeny was a time period of mountain building in western North America, which started in the Late Cretaceous, 70 to 80 million years ago, and ended 35 to 55 million years ago. The exact duration and ages of beginning and end of the orogeny are in dispute. The Laramide orogeny occurred in a series of pulses, with quiescent phases intervening. The major feature that was created by this orogeny was deep-seated, thick-skinned deformation, with evidence of this orogeny found from Canada to northern Mexico, with the easternmost extent of the mountain-building represented by the Black Hills of South Dakota. The phenomenon is named for the Laramie Mountains of eastern Wyoming. The Laramide orogeny is sometimes confused with the Sevier orogeny, which partially overlapped in time and space. The orogeny is commonly attributed to events off the west coast of North America, where the Kula Plate, Kula and Farallon Plates were sliding under the North American plate. Most hypothes ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Southern Rocky Mountains
The Southern Rocky Mountains are a major subregion of the Rocky Mountains of North America located in the southeastern portion of the U.S. state of Wyoming, the central and western portions of Colorado, the northern portion of New Mexico, and extreme eastern portions of Utah. The Southern Rocky Mountains are also commonly known as the Southern Rockies, and since the #Mountain peaks, highest peaks are located in the State of Colorado, they are sometimes known as the Colorado Rockies, although many important ranges and peaks rise in the other three states. The Southern Rockies include the highest mountain ranges of the Rocky Mountains and include all 30 of the Mountain peaks of the Rocky Mountains#Highest peaks, highest major peaks of the Rockies. The Southern Rocky Mountains are generally divided from the Western Rocky Mountains by the Green River (Colorado River), Green River and the Colorado River below the Green River.

Flat Tops (Colorado)
The Flat Tops is a mountain range located in Colorado within the Routt and White River National Forests. Much of the range is within the boundary of the Flat Tops Wilderness Area. While there are notable peaks in the Flat Tops, the dominant feature of the range is the high plateau from which the peaks arise. The plateau forms the northeastern portion of the White River Uplift capped by horizontal basalt flows from tertiary volcanic activity and is bounded by steep drops to valleys carved out by subsequent glaciation. The resulting mix of areas of treeless plateau at an elevation of 11,000 to 12,000 feet interspersed with verdant valleys is unique among Colorado mountain ranges. The area contains approximately one hundred and ten ponds and lakes and is home to a wide variety of plants and animals, including many large mammals such as moose, elk, mule deer, black bear, and cougars. This area has been affected by the non-native plant species, yellow toadflax. The most common tre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
