Bryce Canyon National Park
Bryce Canyon National Park () is an American national park located in southwestern Utah. The major feature of the park is Bryce Canyon, which despite its name, is not a canyon, but a collection of giant natural amphitheaters along the eastern side of the Paunsaugunt Plateau. Bryce is distinctive due to geological structures called hoodoos, formed by frost weathering and stream erosion of the river and lake bed sedimentary rocks. The red, orange, and white colors of the rocks provide spectacular views for park visitors. Bryce Canyon National Park is much smaller and sits at a much higher elevation than nearby Zion National Park. The rim at Bryce varies from . The Bryce Canyon area was settled by Mormon pioneers in the 1850s and was named after Ebenezer Bryce, who homesteaded in the area in 1874. The area around Bryce Canyon was originally designated as a national monument by President Warren G. Harding in 1923 and was redesignated as a national park by Congress in 1928. Th ...

Garfield County, Utah
Garfield County is a county in south central Utah, United States. As of the 2010 United States Census the population was 5,172, making it the fifth-least populous county in Utah; with about 0.98 inhabitants per square mile, it is also the least densely populated county in Utah. Its county seat and largest city is Panguitch. History The Utah Territory legislature created the county on March 9, 1882, with areas partitioned from Iron County. It was named for James A. Garfield, the twentieth President of the United States, who had died six months earlier. The border with Iron County was adjusted in 1884, and Garfield County's boundaries have remained intact since then. Geography The Colorado River, flowing southwestward through a deep gorge, forms the eastern boundary. The Dirty Devil River flows southward through the east end of the county to discharge into Colorado at the county's border. Westward, the cliffs of tributary canyons give way to the barren stretches of the San Raf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Monument (United States)
In the United States, a national monument is a protected area that can be created from any land owned or controlled by the federal government by proclamation of the President of the United States or an act of Congress. National monuments protect a wide variety of natural and historic resources, including sites of geologic, marine, archaeological, and cultural importance. In contrast, national parks in the U.S. cannot be created by presidential proclamation; they require legislation by Congress "because of some outstanding scenic feature or natural phenomena", and serve "inspirational, educational, and recreational values." Some national monuments were first created by presidential action and later designated as national parks by congressional approval. The 129 national monuments are managed by several federal agencies: the National Park Service, United States Forest Service, United States Fish and Wildlife Service, the Bureau of Land Management, and the National Oceanic and ...

Henry Mountains
The Henry Mountains is a mountain range located in the southeastern portion of the U.S. state of Utah that runs in a generally north-south direction, extending over a distance of about . They were named by Almon Thompson in honor of Joseph Henry, the first secretary of the Smithsonian Institution. The nearest town of any size is Hanksville, Utah, which is north of the mountains. The Henry Mountains were the last mountain range to be added to the map of the 48 contiguous U.S. states (1872), and before their official naming by Thompson were sometimes referred to as the "Unknown Mountains." In Navajo, the range is still referred to as ''Dził Bizhiʼ Ádiní'' ("mountain whose name is missing"). The great majority of the land within the Henry Mountains is owned by the U.S. Bureau of Land Management. A herd of 350 American Bison roams freely in the Henrys. Geography and geology The range is clustered into two main groups, with Highway 276 dividing the two portions. The northern ...

Markagunt Plateau
Markagunt Plateau is a volcanic field in southern Utah, United States. Formed in a region of older volcanics, it consists of several cinder cones and associated lava flows. Some of the lava flows feature lava tubes such as Mammoth Cave, while others have formed lava dams and lakes like Navajo Lake. Volcanism took place during the Pliocene and latest Pleistocene but may have continued into the Holocene; legends of the Southern Paiute may reflect past eruptions. Geography and geomorphology The Markagunt Plateau is in southern Utah in the counties Iron County, Garfield County and Kane County. Cedar City lies west and Kanab south of the volcanic field, which is crossed by Utah State Route 14, Utah State Route 143 and Utah State Route 148. Towns in the area include Duck Creek Village and Mammoth Creek. The volcanic field is on a plateau bordered to the south by the Pink Cliffs and to the west by the cliffs of Cedar Breaks National Monument, and features lava flows and over 25 ...

Cedar Breaks National Monument
Cedar Breaks National Monument is a U.S. National Monument located in the U.S. state of Utah near Cedar City. Cedar Breaks is a natural amphitheater, stretching across , with a depth of over . The elevation of the rim of the amphitheater is over above sea level. Rising above the rim is the prominent Brian Head, the peak of which lies a short distance outside of the National Monument boundary. The rock of the amphitheater is more eroded than, but otherwise similar to, formations at nearby Bryce Canyon National Park, Red Canyon in Dixie National Forest, and select areas of Cedar Mountain (SR-14). Because of its elevation, snow often makes parts of the park inaccessible to vehicles from October through May. Its rim visitor center is open from June through October. Several hundred thousand people visit the monument annually. The monument area is the headwaters of Mammoth Creek, a tributary of the Sevier River. Flora and fauna Wildlife can often be seen in this high altitude s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headward Erosion
Headward erosion is erosion at the origin of a stream channel, which causes the origin to move back away from the direction of the stream flow, lengthening the stream channel.Essentials of Geology, 3rd Ed, Stephen Marshak It can also refer to widening of a canyon by erosion along its very top edge, when sheets of water first enter the canyon from a more roughly planar surface above it, such as at Canyonlands National Park in Utah. When sheets of water on a roughly planar surface first enter a depression in it, this erodes the top edge of the depression. The stream is forced to grow longer at the very top of the stream, which moves its origin back, or causes the canyon formed by the stream to grow wider as the process repeats. Widening of the canyon by erosion inside the canyon, below the canyon side top edge, or origin or the stream, such as erosion caused by the streamflow inside it, is not called headward erosion. Headward erosion is a fluvial process of erosion that lengthe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical ero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paria River
The Paria River is a tributary of the Colorado River, approximately long, in southern Utah and northern Arizona in the United States. It drains a rugged and arid region northwest of the Colorado, flowing through roadless slot canyons along part of its course. Geography It is formed in southern Utah, in southwestern Garfield County from several creeks that descend from the edge of the Paunsaugunt Plateau, meeting just north of Tropic. It flows SSE across Kane County and Grand Staircase–Escalante National Monument. Along the Arizona state line, it descends through the Vermilion Cliffs in the Paria Canyon and onto the Paria Plateau. It joins the Colorado from the northwest approximately 5 mi (8 km) southwest of Page, Arizona and the Glen Canyon Dam. The lower 20 mi (32 km) of the river are within the Paria Canyon-Vermilion Cliffs Wilderness, which is administered by the Bureau of Land Management; a permit is required for any overnight visit.

Colorado River Numic Language
Colorado River Numic (also called Ute , Southern Paiute , Ute–Southern Paiute, or Ute-Chemehuevi ), of the Numic branch of the Uto-Aztecan language family, is a dialect chain that stretches from southeastern California to Colorado. Individual dialects are Chemehuevi, which is in danger of extinction, Southern Paiute (Moapa, Cedar City, Kaibab, and San Juan subdialects), and Ute (Central Utah, Northern, White Mesa, Southern subdialects). According to the '' Ethnologue'', there were a little less than two thousand speakers of Colorado River Numic Language in 1990, or around 40% out of an ethnic population of 5,000. The Southern Paiute dialect has played a significant role in linguistics, as the background for a famous article by linguist Edward Sapir and his collaborator Tony Tillohash on the nature of the phoneme. Dialects The three major dialect groups of Colorado River are Chemehuevi, Southern Paiute, and Ute, although there are no strong isoglosses. The threefold divisio ...
