Canyon Lands
The Canyon Lands Section of the Colorado Plateau is a physiographic section of the larger Colorado Plateaus province, which in turn is part of the larger Intermontane Plateaus physiographic division in the Western United States Description The Canyon Lands are a desolate, but spectacularly scenic sandstone area of southeastern Utah and northeastern Arizona. Dominated by canyons (as the name implies) this section has four large upwarps between which are structural basins. Very little faulting is associated with the upwarps or basins. Other distinctive features of the Canyon Lands Section are the laccolithic mountains, like the Henry Mountains and the La Sal Mountains. These are structural domes. The turbid San Juan River flows into the region from the east, through a deep meandering gorge, which, with its tributaries, drains a far-reaching area, including the La Plata Mountains, the San Juan Mountains and other lesser ranges on the Continental Divide, the Chuska Mountains, and en ...

Canyonlands Section
Canyonlands National Park is an American national park located in southeastern Utah near the town of Moab, Utah, Moab. The park preserves a colorful landscape eroded into numerous canyons, mesas, and buttes by the Colorado River, the Green River (Colorado River), Green River, and their respective tributaries. Legislation creating the park was signed into law by President Lyndon Johnson on September 12, 1964. The park is divided into four districts: the Island in the Sky, the Needles, the Maze, and the combined rivers—the Green and Colorado—which carved two large canyons into the Colorado Plateau. While these areas share a primitive desert atmosphere, each retains its own character. Author Edward Abbey, a frequent visitor, described the Canyonlands as "the most weird, wonderful, magical place on earth—there is nothing else like it anywhere." History In the early 1950s, Bates Wilson, then superintendent of Arches National Park, Arches National Monument, began exploring the ...

Wasatch Range
The Wasatch Range ( ) or Wasatch Mountains is a mountain range in the western United States that runs about from the Utah-Idaho border south to central Utah. It is the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region.''Hiking the Wasatch'', John Veranth, 1988, Salt Lake City, The northern extension of the Wasatch Range, the Bear River Mountains, extends just into Idaho, constituting all of the Wasatch Range in that state. In the language of the native Ute people, Wasatch means "mountain pass" or "low pass over high range." According to William Bright, the mountains were named for a Shoshoni leader who was named with the Shoshoni term ''wasattsi'', meaning "blue heron". In 1926, Cecil Alter quoted Henry Gannett from 1902, who said that the word meant "land of many waters," then posited, "the word is a common one among the Shoshones, and is given to a berry basket" carried by women.

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian. In parts of Europe, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emery County, Utah
Emery County is a county in east-central Utah, United States. As of the 2010 United States Census, the population was 10,976. Its county seat is Castle Dale, and the largest city is Huntington. History Prehistory Occupation of the San Rafael region dates back thousands of years to include people of the Desert Archaic Culture who were followed by those of the Fremont culture who inhabited present-day Emery County through the sixth through thirteenth centuries AD. Evidence of these civilizations is extant in numerous pictograph and petroglyph panels, such as those in Temple Mountain Wash, Muddy Creek, Ferron Box, Black Dragon Canyon, and Buckhorn Wash - all sites listed in the National Register of Historic Places. Ute Indians also occupied sites in Castle Valley, Old Spanish Trail The first non-indigenous persons to view Castle Valley were Spanish Traders and Explorers. The first of record was Silvestre Vélez de Escalante; in 1776, he crossed northern Utah through the Uintah ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Rafael Swell
The San Rafael Swell is a large geologic feature located in south-central Utah, United States about west of Green River. The San Rafael Swell, measuring approximately , consists of a giant dome-shaped anticline of sandstone, shale, and limestone that was pushed up during the Paleocene Laramide Orogeny 60–40 million years ago. Since that time, infrequent but powerful flash floods have eroded the sedimentary rocks into numerous valleys, canyons, gorges, mesas, buttes, and badlands. The swell is part of the Colorado Plateau physiographic region. Geography Interstate 70 divides the Swell into northern and southern sections, and provides the only interstate access to the region. The swell lies entirely within Emery County. The northern Swell is drained mainly by the San Rafael River, while the southern Swell is drained mainly by Muddy Creek, which eventually joins the Fremont River to become Dirty Devil River northeast of Hanksville, Utah. The Dirty Devil River flows southward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Mesa (Apache-Navajo Counties, Arizona)
Black Mesa (also called Big Mountain) is an upland mountainous mesa of Arizona, north-trending in Navajo County, west and southeast-trending in Apache County. In Navajo it is called ('Black Mountain') and during Mexican rule of Arizona it was called Mesa de las Vacas (Spanish for 'mesa of the cows'). It derives its dark appearance from its pinyon-juniper and mixed conifer woodlands. Geography The mesa is located on the Colorado Plateau near Kayenta, Arizona, and rises to over 8168 feet. Its highest peak is located on Black Mesa's northern rim, a few miles south of the town of Kayenta. Reliable springs surfacing at several locations mean the mesa is more suitable for continuous habitation than much of the surrounding desert area. It is now split between the Hopi and Diné (Navajo) tribal reservations. Black Mesa is also the name of a small Navajo community off BIA-8066, which lies 17 miles west of Rough Rock, 20 miles north of Blue Gap and 25 miles northeast of Pinon. I ...

Painted Desert (Arizona)
The Painted Desert is a United States desert of badlands in the Four Corners area, (cited by ) running from near the east end of Grand Canyon National Park and southeast into Petrified Forest National Park. It is most easily accessed from the north portion of Petrified Forest National Park. The Painted Desert is known for its brilliant and varied colors: these include the more common red rock, but also shades of lavender. History The Painted Desert was named by a Spanish expedition under Francisco Vázquez de Coronado during his 1540 quest to find the Seven Cities of Cibola. He located these some east of Petrified Forest National Park. Finding the cities were not made of gold, Coronado sent an expedition to find the Colorado River to gain supplies. Passing through the wonderland of colors, they named the area ''El Desierto Pintado'' ("The Painted Desert"). Much of the Painted Desert within Petrified Forest National Park is protected as Petrified Forest National Wilderness A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Colorado River
The Little Colorado River () is a tributary of the Colorado River in the U.S. state of Arizona, providing the principal drainage from the Painted Desert region. Together with its major tributary, the Puerco River, it drains an area of about in eastern Arizona and western New Mexico. Although it stretches almost , only the headwaters and the lowermost reaches flow year-round. Between St. Johns and Cameron, most of the river is a wide, braided wash, only containing water after heavy snowmelt or flash flooding. The lower is known as the Little Colorado River Gorge and forms one of the largest arms of the Grand Canyon, at over deep where it joins the Colorado near Desert View in Grand Canyon National Park. An overlook of the gorge is a Navajo Nation Tribal Park. Course The river rises as two forks in the White Mountains of mid-eastern Arizona, in Apache County. The West Fork starts in a valley on the north flank of Mount Baldy at an elevation of nearly , while the East For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuesta
A cuesta (from Spanish ''cuesta'' "slope") is a hill or ridge with a gentle slope on one side, and a steep slope on the other. In geology the term is more specifically applied to a ridge where a harder sedimentary rock overlies a softer layer, the whole being tilted somewhat from the horizontal. This results in a long and gentle backslope called a dip slope that conforms with the dip of resistant strata, called caprock. Where erosion has exposed the frontslope of this, a steep slope or escarpment occurs. The resulting terrain may be called scarpland. Definition In general usage, a cuesta is a hill or ridge with a gentle slope (backslope) on one side, and a steep slope (frontslope) on the other. The word is from Spanish: "flank or slope of a hill; hill, mount, sloping ground". In geology and geomorphology, cuesta refers specifically to an asymmetric ridge with a long and gentle backslope called a dip slope that conforms with the dip of a resistant stratum or strata, called cap ...

Mesa Verde
Mesa Verde National Park is an American national park and UNESCO World Heritage Site located in Montezuma County, Colorado. The park protects some of the best-preserved Ancestral Puebloan archaeological sites in the United States. Established by Congress and President Theodore Roosevelt in 1906, the park occupies near the Four Corners region of the American Southwest. With more than 5,000 sites, including 600 cliff dwellings, it is the largest archaeological preserve in the United States. Mesa Verde (Spanish for "green table", or more specifically "green table mountain") is best known for structures such as Cliff Palace, thought to be the largest cliff dwelling in North America. Starting BC Mesa Verde was seasonally inhabited by a group of nomadic Paleo-Indians known as the Foothills Mountain Complex. The variety of projectile points found in the region indicates they were influenced by surrounding areas, including the Great Basin, the San Juan Basin, and the Rio Grande Vall ...
