San Rafael Reef
The San Rafael Reef is a geologic feature located in Emery County in central Utah Utah is a landlocked state in the Mountain states, Mountain West subregion of the Western United States. It is one of the Four Corners states, sharing a border with Arizona, Colorado, and New Mexico. It also borders Wyoming to the northea ..., part of the Colorado Plateau. Approximately 75 miles (120 km) long, it is the distinctive eastern edge of the San Rafael Swell. Composed primarily of steeply tilted layers of Navajo and Wingate Sandstone, it has been eroded into tall fins, domes, cliffs, and deep canyons. The San Rafael River, Interstate 70, and Muddy Creek all cut through the San Rafael Reef. There are also numerous slot canyons that twist their way through the flanks of the San Rafael Reef, among them Crack Canyon, Chute Canyon and Straight Wash. These spectacularly beautiful canyons are often just a few feet wide and can be hundreds of feet deep. Wilderness The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emery County, Utah
Emery County is a County (United States), county in east-central Utah, United States. As of the 2020 United States census, the population was 9,825. Its county seat is Castle Dale, Utah, Castle Dale, and the largest city is Huntington, Utah, 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 (Utah), Muddy Creek, Ferron Box, Black Dragon Canyon, and Buckhorn Draw Pictograph Panel, Buckhorn Wash - all sites listed in the National Register of Historic Places.

Interstate 70
Interstate 70 (I-70) is a major east–west Interstate Highway in the United States that runs from Interstate 15, I-15 near Cove Fort, Utah, to Interstate 695 (Maryland), I-695 and Maryland Route 570 (MD 570) in Woodlawn, Baltimore County, Maryland, Woodlawn, just outside Baltimore, Maryland. I-70 approximately traces the path of U.S. Route 40 (US 40; the old National Road) east of the Rocky Mountains. West of the Rocky Mountains, the route of I-70 was derived from multiple sources. The Interstate runs through or near many major U.S. cities, including Denver, Topeka, Kansas, Topeka, Kansas City, Missouri, Kansas City, St. Louis, Indianapolis, Columbus, Ohio, Columbus, Pittsburgh, and Baltimore. The sections of the Interstate in Missouri and Kansas have laid claim to be the first Interstate in the United States. The Federal Highway Administration (FHWA) has claimed the section of I-70 through Glenwood Canyon in Colorado, completed in 1992, to be the last pie ...

Bureau Of Land Management
The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands, U.S. federal lands. Headquartered in Washington, D.C., the BLM oversees more than of land, or one-eighth of the United States's total landmass. The Bureau was created by United States Congress, Congress during the presidency of Harry S. Truman in 1946 by combining two existing agencies: the United States General Land Office and the United States Grazing Service, Grazing Service. The agency manages the federal government's nearly of subsurface Mineral rights, mineral estate located beneath federal, state and private lands severed from their surface rights by the Homestead Act of 1862.

Wilderness Area
Wilderness or wildlands (usually in the plural) are Earth's natural environments that have not been significantly modified by human activity, or any nonurbanized land not under extensive agricultural cultivation. The term has traditionally referred to terrestrial environments, though growing attention is being placed on marine wilderness. Recent maps of wilderness suggest it covers roughly one-quarter of Earth's terrestrial surface, but is being rapidly degraded by human activity. Even less wilderness remains in the ocean, with only 13.2% free from intense human activity. Some governments establish protection for wilderness areas by law to not only preserve what already exists, but also to promote and advance a natural expression and development. These can be set up in preserves, conservation preserves, national forests, national parks and even in urban areas along rivers, gulches or otherwise undeveloped areas. Often these areas are considered important for the surviva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 70 In Utah
Interstate 70 (I-70) is a mainline route of the Interstate Highway System in the United States connecting Utah and Maryland. The Utah section runs east–west for approximately across the central part of the state. Richfield is the largest Utah city served by the freeway, which does not serve or connect any urban areas in the state. The freeway was built as part of a system of highways connecting Los Angeles and the Northeastern United States. I-70 was the second attempt to connect southern California to the east coast of the United States via central Utah, the first being a failed attempt to construct a transcontinental railroad. Parts of that effort were reused in the laying out of the route of I-70. Unlike most Interstate Highways, much of I-70 in Utah was not constructed parallel to or on top of an existing U.S. Route. Portions of I-70 were constructed in areas where previously there were no paved roads. Because it was built over an entirely new route, I-70 has many ...

San Rafael Desert
The San Rafael Swell is a large geologic feature located in south-central Utah, United States about west of Green River. Measuring approximately , the swell consists of a giant dome-shaped anticline of sandstone, shale, and limestone that was pushed up during the Paleocene Laramide Orogeny 40–60 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] |
Contrails
Contrails (; short for "condensation trails") or vapour trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several kilometres/miles above the Earth's surface. They are composed primarily of water, in the form of ice crystals. The combination of water vapor in aircraft engine exhaust and the low ambient temperatures at high altitudes causes the trails' formation. Impurities in the engine exhaust from the fuel, including soot and sulfur compounds (0.05% by weight in jet fuel) provide some of the particles that serve as cloud condensation nuclei for water droplet growth in the exhaust. If water droplets form, they can freeze to form ice particles that compose a contrail. Their formation can also be triggered by changes in air pressure in wingtip vortices, or in the air over the entire wing surface. Contrails, and other clouds caused directly by human activity, are called ''homogenitus''. The vapor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muddy Creek (Utah)
Muddy Creek is a stream in central Utah, United States, that drains portions of Emery, Sanpete, Sevier, and Wayne counties. Description The creek begins on the eastern slopes of the Wasatch Plateau at elevations above . It turns southward near the town of Emery, then southeastward, where it crosses under Interstate 70. It then directly enters the western flank of the San Rafael Swell and continuing in a southeasterly direction, it passes Hondu Arch, and the Tomsich Butte mining area then begins its spectacular passage through a narrow slot canyon of Coconino Sandstone known as the "Chute". After merging with Chimney Canyon and passing the Hidden Splendor Mine area, it passes through the southeastern escarpment of the San Rafael Reef at the end of Muddy Creek Gorge. In its lower reaches, it continues southeastward through the Blue Hills badlands near Caineville, then cuts through the Jurassic Morrison Formation where dinosaur fossils have been found. Finally, after an estim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Rafael River (Utah)
The San Rafael River is a tributary of the Green River, approximately long, in east central Utah, United States. The river flows across a sparsely populated arid region of the Colorado Plateau, and is known for the isolated, scenic gorge through which it flows. Description The river rises in northwestern Emery County, approximately southeast of Castle Dale, by the confluence of Cottonwood, Huntington and Ferron creeks, which provide its headwaters in the Wasatch Plateau region. It flows east-southeast along the north side of the Coal Cliffs and the prominent anticline called the San Rafael Swell, passing north of Window Butte (Window Blind Peak) and through two narrow slot canyons in Coconino Sandstone called the Upper and Lower Black Box. This area is known as the San Rafael Gorge, sometimes called the "Little Grand Canyon". (Actually, the "Little Grand Canyon" is a few miles upstream where the San Rafael passes between the Wedge on the north and Sid's Mountain and No Man' ...

Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingate Sandstone
The Wingate Sandstone is a geologic formation in the Glen Canyon Group of the Colorado Plateau province of the United States which crops out in northern Arizona, northwest Colorado, Nevada, and Utah. Geology Wingate Sandstone is particularly prominent in southeastern Utah, where it forms attractions in a number of national parks and monuments. These include Capitol Reef National Park, the San Rafael Swell, and Canyonlands National Park. Wingate Sandstone frequently appears just below the Kayenta Formation and Navajo Sandstone, two other formations of the Glen Canyon group. Together, these three formations can result in immense vertical cliffs of or more. Wingate layers are typically pale orange to red in color, the remnants of wind-born sand dunes deposited approximately 200 million years ago in the Late Triassic. Fossil content Long dated to the Early Jurassic only, fossils (including a phytosaur skull) and other evidence indicate that part of the Wingate Sandstone is ...
