Red Cliffs National Conservation Area
The Red Cliffs National Conservation Area is a National Conservation Area located in southwest Utah, north of St. George at the northeasternmost edge of the Mojave Desert. It is managed by the Bureau of Land Management as part of the National Landscape Conservation System, and was created as part of the Omnibus Public Land Management Act of 2009. The Red Cliffs National Conservation Area (NCA) is part of the larger multi-jurisdictional Red Cliffs Desert Reserve, which was created in 1996 to protect the habitat and populations of the desert tortoise and other species. Part of the NCA was designated in 2009 as the Cottonwood Canyon and Red Mountain wilderness areas, which are part of the National Wilderness Preservation System. The Pine Valley Mountains and Dixie National Forest are north of the NCA. The NCA is located within the watershed of the Virgin River, a tributary of the Colorado River.

National Wilderness Preservation System
The National Wilderness Preservation System (NWPS) of the United States protects federally managed wilderness areas designated for preservation in their natural condition. Activity on formally designated wilderness areas is coordinated by the National Wilderness Preservation System. Wilderness areas are managed by four federal land management agencies: the National Park Service, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management. The term ''wilderness'' is defined as "an area where the earth and community of life are untrammeled by man, where man himself is a visitor who does not remain" and "an area of undeveloped Federal land retaining its primeval character and influence, without permanent improvements or human habitation, which is protected and managed so as to preserve its natural conditions". , 803 wilderness areas have been designated, totaling , which comprise about 4.5% of the land area of the United States.

Protected Areas Of Washington County, Utah
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage serving ...

Cross-bedding
In geology, cross-bedding, also known as cross-stratification, is layering within a stratum and at an angle to the main bedding plane. The sedimentary structures which result are roughly horizontal units composed of inclined layers. The original depositional layering is tilted, such tilting not being the result of post-depositional deformation. Cross-beds or "sets" are the groups of inclined layers, which are known as cross-strata. Cross-bedding forms during deposition on the inclined surfaces of bedforms such as ripples and dunes; it indicates that the depositional environment contained a flowing medium (typically water or wind). Examples of these bedforms are ripples, dunes, anti-dunes, sand waves, hummocks, bars, and delta slopes.Collinson, J.D., Thompson, D.B., 1989, Sedimentary Structures (2nd ed): Academic Division of Unwin Hyman Ltd, Winchester, MA, XXX p.

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid drainage basin, watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the Mexico–United States border, international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven National parks of the United States, U.S. National Parks, the Colorado River and its tributaries are a v ...

Virgin River
The Virgin River is a tributary of the Colorado River in the U.S. states of Utah, Nevada, and Arizona. The river is about long.Calculated with Google Maps and Google Earth It was designated Utah's first wild and scenic river in 2009, during the centennial celebration of Zion National Park. History The first known Euro-American party to encounter the Virgin was led by Jedediah Smith in 1826. Smith named it "Adams River", after then-president John Quincy Adams.Smith, Jedediah S., arrison G. Rogers and George R. Brooks (ed.). ''The Southwest Expedition of Jedediah S. Smith: His Personal Account of the Journey to California, 1826–1827'', p. 55. Lincoln and London, University of Nebraska Press, 9771989. Later explorer and mapmaker John C. Fremont reported that it was called "Rio Virgen" but did not state the origin of the name. Hiram Chittenden speculated that Smith had later renamed the river after Thomas Virgin, who was badly wounded in an 1827 attack by Mohave people during ...

Pine Valley Mountains
The Pine Valley Mountains are a mountain range in Washington County, Utah, United States, spanning the county north of the city of St. George. The highest point in the range is Signal Peak at . The mountains are part of Dixie National Forest and are bordered to the south by the Red Cliffs National Conservation Area. Geology The Pine Valley Mountains formed from the Pine Valley Laccolith, the largest laccolith in the United States and perhaps the world. The laccolith was formed during a 20 million-year period of volcanic activity. After 4-5,000 feet of volcanic deposited on the Claron Formation, the magma vents were effectively sealed off. A final surge of magma, unable to find its way to the surface, pushed sideways along the weak seam between the Claron and the overlying volcanic layers. This injected a 3,000 foot-thick layer of monzonite porphyry to form the Pine Valley laccolith. The contact between the top of the Claron and the bottom of the laccolith can be seen in sever ...

Red Mountain Wilderness (Utah)
The Red Mountain Wilderness (Utah) is a wilderness area in the US state of Utah. It was designated March 30, 2009, as part of the Omnibus Public Land Management Act of 2009. Located six miles northeast of St. George, it is bordered by Snow Canyon State Park to the east and the Shivwitz Indian Reservation to the southwest. Approximately one-half of the wilderness is located within the recently designated Red Cliffs National Conservation Area. Prehistoric use by the Southern Paiute Indians has been documented at seven sites in the area, and the BLM estimates archeological site densities between 4 and 40 per square mile. The namesake of the wilderness is Red Mountain, a great block of Navajo sandstone bounded by the Gunlock Fault on the west, and by the Santa Clara River valley and Snow Canyon on the south and east. Vegetation The mixing of species from the Mojave and Great Basin deserts makes for unusually diverse vegetation in the Red Mountains Wilderness, which includes pin ...
