Kelso Wash
Kelso Wash is an ephemeral stream in San Bernardino County, California, United States, that drains into Soda Lake . The town of Kelso lies southeast of the wash . Kelso Wash lies within the Mojave National Preserve. It originates at Cima, between the Kelso Mountains to the west and the Providence Mountains to the east as a southward flowing wash , where it receives the Cedar Wash from northeast and washes draining the Marl Mountains from northwest. The Cima Dome lies nearby. The area of Cima separates its valley from Ivanpah Valley . It then turns west north of the Kelso Dunes and receives first the Cottonwood Wash from southeast, which drains the southern Providence Mountains and the Granite Mountains , and then the Budweiser Wash from the south, which drains the Bristol Mountains, Granite Mountains and Old Dad Mountains. Kelso Wash then passes northwestward between Devils Playground to the north and Bristol Mountains to the south. It eventually ends into Soda Lake . It is t ...

Mojave National Preserve
Mojave National Preserve is a United States National Preserve located in the Mojave Desert of San Bernardino County, California, USA, between Interstate 15 in California, Interstate 15 and Interstate 40. The preserve was established October 31, 1994, with the passage of the California Desert Protection Act by the US Congress, which also established Joshua Tree National Park and Death Valley National Park as National park, National Parks. Previously, some lands contained within the Preserve were the East Mojave National Scenic Area, under the jurisdiction of the Bureau of Land Management. At , within the contiguous United States it is the third largest unit of the National Park System and the first largest National preserve, National Preserve. The preserve was created within the Pacific West Region of the National Park Service and remains within that jurisdiction today. Natural features include the Kelso Dunes, the Marl Mountains and the Cima Dome & Volcanic Field National Natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Mountains
The Bristol Mountains are found in the Mojave Desert of California, USA, just west of Mojave National Preserve. The range, which reaches an elevation of 3,874 feet (1,181 m), is located in San Bernardino County, and crosses Interstate 40 between Ludlow and the Granite Mountains. At the southern end of the range lies the town of Amboy, the Amboy Crater, and Bristol Dry Lake. Bristol Mountains Wilderness Area Most of the Bristol Mountains is in a Federally designated Wilderness and lies within either thBristol Mountains Wilderness Areaor th The remainder of the range is designated for Wilderness status in the proposed California Desert Protection Act of 2010. Project Carryall, proposed in 1963 by the Atomic Energy Commission, the California Division of Highways (now called Caltrans), and the Santa Fe Railway, would have used 22 nuclear explosions to excavate a massive roadcut through the Bristol Mountains in the Mojave Desert, to accommodate construction of Interstate 40 and a n ...

Mojave River
The Mojave River is an intermittent river in the eastern San Bernardino Mountains and the Mojave Desert in San Bernardino County, California, United States. Most of its flow is underground, while its surface channels remain dry most of the time, except for the headwaters and several bedrock gorges in the lower reaches. History A desert branch of the Serrano Native Americans called the ''Vanyume'' or ''Beñemé'', as Father Garcés called them, lived beyond and along much of the length of the Mojave River, from east of Barstow to at least the Victorville region, and perhaps even farther upstream to the south, for up to 8,000 years in a series of villages, including the major village of Wá’peat. The Mohave's trail, later the European immigrants' Mojave Road, ran west from their villages on the Colorado River to Soda Lake, then paralleled the river from its mouth on the lake to the Cajon Pass. Native Americans used this trade route where water could easily be found en route ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Pacific Railroad
The Union Pacific Railroad , legally Union Pacific Railroad Company and often called simply Union Pacific, is a freight-hauling railroad that operates 8,300 locomotives over routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second largest railroad in the United States after BNSF, with which it shares a duopoly on transcontinental freight rail lines in the Western, Midwestern and Southern United States. Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route. Over the next century, UP absorbed the Missouri Pacific Railroad, the Chicago and North Western Transportation Company, the Western Pacific Railroad, the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad. In 1996, the Union Pacific merged with Southern Pacific Transportation Company, itself a giant system that was absorbed by the Denver and Rio Grande Western Railroad ...

River Terrace
Fluvial terraces are elongated terraces that flank the sides of floodplains and fluvial valleys all over the world. They consist of a relatively level strip of land, called a "tread", separated from either an adjacent floodplain, other fluvial terraces, or uplands by distinctly steeper strips of land called "risers". These terraces lie parallel to and above the river channel and its floodplain. Because of the manner in which they form, fluvial terraces are underlain by fluvial sediments of highly variable thickness.Fairbridge, R. W., 1968, ''Encyclopedia of Geomorphology.'' Reinhold Book Company, New York.Blum, M., and T.E. Tonqvist, 2000, ''Fluvial responses to climate and sea-level change, a review and look forward.'' Sedimentology. v. 47 suppl. 1, pp. 2-48. River terraces are the remnants of earlier floodplains that existed at a time when either a stream or river was flowing at a higher elevation before its channel downcut to create a new floodplain at a lower elevation.

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...
