Worthington Peak
Worthington Peak is an mountain summit located in Lincoln County, Nevada, United States. Description Worthington Peak is the highest summit in the Worthington Mountains which are a subset of the Great Basin Ranges. This remote peak is set in the Basin and Range National Monument on land managed by the Bureau of Land Management. It is situated on the boundary of the Worthington Mountains Wilderness, north of Meeker Peak, north of Las Vegas, and northeast of Nellis Air Force Base Complex. Topographic relief is significant as the summit rises above Garden Valley in two miles, and above Sand Springs Valley in three miles. The peak is composed primarily of limestone with some sandstone, with abundant fossils of the Silurian within the limestone. This landform's toponym has been officially adopted by the U.S. Board on Geographic Names. The name was applied by the Wheeler Survey and has been printed in publications since 1877.

Mountains Of Nevada
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 ...

Great Basin
The Great Basin is the largest area of contiguous endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrographic, biological, floristic, physiographic, topographic, and ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature of the landform as "having no connection to the ocean". The hydrographic definition is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diurnal Temperature Variation
In meteorology, diurnal temperature variation is the variation between a high air temperature and a low temperature that occurs during the same day. Temperature lag Temperature lag is an important factor in diurnal temperature variation: peak daily temperature generally occurs ''after'' noon, as air keeps net absorbing heat even after noon, and similarly minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long. The analogous annual phenomenon is seasonal lag. As solar energy strikes the Earth's surface each morning, a shallow layer of air directly above the ground is heated by conduction. Heat exchange between this shallow layer of warm air and the cooler air above is very inefficient. On a warm summer's day, for example, air temperatures may vary by from just above the ground to waist height. Incoming solar radiation exceeds outgoing heat energy for many hours af ...

Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used Isotherm (contour line), isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classi ...

Great Basin Desert
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey. It is a temperate desert with hot, dry summers and snowy winters. The desert spans large portions of Nevada and Utah, and extends into eastern California. The desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts. Basin and range topography characterizes the desert: wide valleys bordered by parallel mountain ranges generally oriented north–south. There are more than 33 peaks within the desert with summits higher than , but valleys in the region are also high, most with elevations above . The biological communities of the Great Basin Desert vary ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Gannett
Henry Gannett (August 24, 1846 – November 5, 1914) was an American geographer who is described as the "father of mapmaking in America."Evans, Richard Tranter; Frye, Helen M. (2009).History of the Topographic Branch (Division) (PDF). ''U.S. Geological Survey Circular''. 1341. . He was the chief geographer for the United States Geological Survey essentially from its founding until 1902. He was also a founding member and president of the National Geographic Society. Background Gannett was born in Bath, Maine, son of Hannah Trufant (nee Church) and Michael Farley Gannett. He attended local schools, before going to Harvard for college. He graduated with a B.S. from the Lawrence Scientific School of Harvard University in 1869 and received an M.E. at the Hooper Mining School (aka the Harvard University School of Mining and Practical Geology) in 1870. From 1870 to 1871, he was an assistant at the Harvard College Observatory. In 1871, he participated in a Harvard expedition to Spain t ...

Wheeler Survey
The Wheeler Survey, carried out in 1872-1879, was one of the "Four Great Surveys" conducted by the US government after the Civil War primarily to document the geology and natural resources of the American West. Supervised by First Lieutenant (later Captain) George Montague Wheeler, the Wheeler Survey documented and mapped the United States west of the 100th meridian. The survey team included Lieutenant (later Brigadier General) Montgomery M. Macomb. Wheeler led early expeditions from 1869 to 1871 in the West, and in 1872 the US Congress authorized an ambitious plan to map the portion of the United States west of the 100th meridian at a scale of eight miles to the inch. This plan necessitated what became known as the Wheeler Survey. The survey's main goal was to make topographic maps of the southwestern United States. In addition he was to ascertain everything related to the physical features of the region; discover the numbers, habits, and disposition of Indians in the sectio ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
