Virgin Mountains
The Virgin Mountains are a mountain range of the northeastern Mojave Desert, located in Clark County, southeastern Nevada and Mohave County, northwestern Arizona. Geography Virgin Peak, at in elevation, is the highest point in the range. The range is northeast of Lake Mead, and around south of the Nevada town of Mesquite. Hydrologically, the range is located in the Lower Colorado—Lake Mead watershed. (USGS Huc 1501), 91.6% of the range is managed by the Bureau of Land Management, with a section of the Virgin Peak area designated within the BLM Virgin Mountain Natural Area. Natural history The range has many species of lizards, as well as the Panamint rattlesnake and glossy snake. Trees found in the range include Single-leaf pinyon pine (''Pinus monophylla''), Arizona cypress (''Cupressus arizonica''), White fir (''Abies concolor''), Douglas fir (''Pseudotsuga menziesii''), and Utah juniper (''Juniperus osteosperma''), and Rocky Mountain juniper (''Juniperus scopul ...

Mountain Ranges Of Arizona
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Virgin River Narrows
The Narrows is the narrowest section of Zion Canyon in Zion National Park, Utah, United States. Situated on the North Fork of the Virgin River and upstream of the main canyon, The Narrows is one of the premier hikes in the park and on the Colorado Plateau. ''The Narrows'' refers to both the bottom-up hike from the Temple of Sinawava to Big Springs, as well as the top-down hike from Chamberlain's Ranch back to the Temple of Sinawava. History Latter-Day Saint Pioneer and Explorer Nephi Johnson was guided to Zion Canyon in November, 1858 by a friendly Paiute Indian, and was probably the first European-American to see The Narrows. Soon after, in 1861 and 1862, the towns of Virgin and Springdale, just south of Zion Canyon, were founded. The next year, Isaac Behunin built a cabin in upper Zion Canyon for summer farming. The Narrows was descended (and named) in 1872 by geologist and explorer Grove Karl Gilbert as part of the Wheeler Survey. His party traveled from Navajo Lake th ...

Virgin River Gorge
The Virgin River Gorge, located between St. George, Utah, and Beaver Dam, Arizona, is a long canyon that has been carved out by the Virgin River in northwest Arizona. The Virgin River rises on the Colorado Plateau and created the topography of both Zion National Park and the Virgin River Gorge. The Gorge connects the southwestern rim of the Colorado Plateau and the northeastern part of the Mojave Desert. Interstate 15 in Arizona, Interstate 15 runs through the canyon and crosses the Virgin River several times. The Virgin River Gorge section of Interstate 15 is one of the most expensive parts of interstate highway ever constructed. Due to the winding of the canyon, the highway within is also noted for its tricky driving conditions. The climate of the canyon is typical of the Mojave Desert with hot summers and mild winters. Flora and fauna in the canyon are also typical of the Mojave. The canyon is popular among rock climbers, hikers, and camping, campers. See also * Beaver D ...

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 ...

Virgin Valley
The Virgin Valley is a valley in northwest Arizona and southeast Nevada on the Virgin River. The Virgin River drains southwest Utah and southeast Nevada; parts of Arizona, especially the Arizona Strip region drain southwards into the Virgin River and Valley. The Virgin Valley begins as the Virgin River exits the Virgin River Gorge between the Beaver Dam Mountains and Wilderness north, and the northeast of the Virgin Mountains on the south of the Gorge. Lake Mead on the Virgin River extends slightly upstream into the Virgin Valley. History The HUMBOLDT COUNTY virgin valley has mines that are rich in opals. The opals were discovered in about 1913. The richest mines were owned by Flora Haines Loughead who had been a writer and a farmer but bought a string of claims after being sent to do a story for the San Francisco Chronicle. She became known as the "Opal Queen" owning the Rainbow, Stonetree and Bonanza mines and the "Giant Tree" Opal Claim. She sold the latter in about 1918 and ...

Stick Insect
The Phasmatodea (also known as Phasmida, Phasmatoptera or Spectra) are an order of insects whose members are variously known as stick insects, stick-bugs, walking sticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles, although this name is shared by both dragonflies and crane flies. They can be generally referred to as phasmatodeans, phasmids, or ghost insects, with phasmids in the family Phylliidae called leaf insects, leaf-bugs, walking leaves, or bug leaves. The group's name is derived from the Ancient Greek ', meaning an apparition or phantom, referring to their resemblance to vegetation while in fact being animals. Their natural camouflage makes them difficult for predators to detect; still, many species have one of several secondary lines of defense in the form of startle displays, spines or toxic secretions. Stick insects from the genera ''Phryganistria'', ''Ctenomorpha'', and ''Phobaeticus'' include the world's long ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
