Creech Air Force Base
Creech Air Force Base is a United States Air Force (USAF) command and control facility in Clark County, Nevada used "to engage in daily Overseas Contingency Operations …of remotely piloted aircraft systems which fly missions across the globe." In addition to an airport, the military installation has the Unmanned Aerial Vehicle Battlelab, associated aerial warfare ground equipment, and unmanned aerial vehicles of the type used in Afghanistan and Iraq. Creech is the aerial training site for the USAF Thunderbirds and "is one of two emergency divert airfields" for the Nevada Test and Training Range. In addition to the airfield, the base includes the "UAV-Logistic and Training Facility", the Joint Unmanned Aerial Systems Center of Excellence, Silver Flag Alpha Regional Training Center, and other military units/facilities.

Pahute Mesa
Pahute Mesa or Paiute Mesa is one of four major nuclear test regions within the Nevada National Security Site (NNSS). It occupies in the northwest corner of the NNSS in Nevada. The eastern section is known as Area 19 and the western section as Area 20. History The Partial Test Ban Treaty of 1963 banned atmospheric nuclear testing. This led to a requirement for an underground test area that could accommodate higher yield tests than Yucca Flat. Pahute Mesa was seen as ideal due to its geology and distance of over from Las Vegas. Holes can be drilled to a depth of more than . This allows tests in the megaton range to be fully contained with minimal ground motion being felt in Las Vegas. Pahute Mesa was thus incorporated into the boundary of the NNSS in late 1963 under an agreement between the United States Atomic Energy Commission and the U.S. Air Force. Geology and climate Pahute Mesa is part of the Tonopah Basin and includes the Silent Canyon caldera complex of the Southwes ...

Groom Lake
Area 51 is the common name of a highly classified United States Air Force (USAF) facility within the Nevada Test and Training Range. A remote detachment administered by Edwards Air Force Base, the facility is officially called Homey Airport or Groom Lake (after the salt flat next to its airfield). Details of its operations are not made public, but the USAF says that it is an open training range, and it is commonly thought to support the development and testing of experimental aircraft and weapons systems. The USAF and CIA acquired the site in 1955, primarily for flight testing the Lockheed U-2 aircraft. The intense secrecy surrounding the base has made it the frequent subject of conspiracy theories and a central component of unidentified flying object (UFO) folklore. It has never been declared a secret base, but all research and occurrences in Area 51 are Top Secret/Sensitive Compartmented Information (TS/SCI). The CIA publicly acknowledged the base's existence on June 25, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 section; ...

Sand Springs-Tikaboo Watershed
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non- tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand, for example, aragonite, which has mostly been created, over the past 500million years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean. Somewhat more rarely, sand may be composed o ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spring Mountains
The Spring Mountains are a mountain range of Southern Nevada in the United States, running generally northwest–southeast along the west side of Las Vegas and south to the border with California. Most land in the mountains is owned by the United States Forest Service and the Bureau of Land Management and managed as the Spring Mountains National Recreation Area within the Humboldt-Toiyabe National Forest and the Red Rock Canyon National Conservation Area. Geography The Spring Mountains range is named for the number of springs to be found, many of them in the recesses of Red Rock Canyon National Conservation Area, which is on the eastern side of the mountains. The Spring Mountains divide the Pahrump Valley and Amargosa River basins from the Las Vegas Valley watershed, which drains into the Colorado River watershed, by way of Las Vegas Wash into Lake Mead, thus the mountains define part of the boundary of the Great Basin. The Great Basin Divide, (one of the Great Basin region b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
