Great Basin
The Great Basin is the largest area of contiguous endorheic watersheds in North America. It spans sections of Wyoming, Idaho, Utah, Nevada, Oregon, California and the Mexican state of 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 to the highest point of the contiguous United States, less than 100 miles (160 km) away at the summit of Mount Whitney

Topography
Topography is the study of the shape and features of the surface of the Earth and other observable astronomical objects including planets, Natural satellite">moons, and asteroids. The topography of an area could refer to the surface shapes and features themselves, or a description (especially their depiction in maps). This field of geoscience and planetary science is concerned with local detail in general, including not only relief but also natural and artificial features, and even local history and culture. This meaning is less common in the United States, where topographic maps with elevation contours have made "topography" synonymous with relief. The older sense of topography as the study of place still has currency in Europe. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms

Ethnography
Ethnography (from Greek Greek language text">ἔθνος ethnos "folk, people, nation" and Greek language text">γράφω grapho "I write") is the systematic study of people and cultures. It is designed to explore cultural phenomena where the researcher observes society from the point of view of the subject of the study. An ethnography is a means to represent graphically and in writing the culture of a group

Ecology
Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of") is the branch of biology which studies the interactions among organisms and their environment. Objects of study include interactions of organisms that include biotic and Abiotic component">abiotic components of their environment. Topics of interest include the biodiversity, distribution, Biomass (ecology)">biomass, and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits

Hydrography
Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defence, scientific research, and environmental protection.

Ecoregion
An ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than an ecozone. All three of these are either less or greater than an ecosystem. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, Fauna (animals)">fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions

Biome
A biome /ˈbm/ is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. "Biome" is a broader term than "habitat"; any biome can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on a human body. A 'biota' is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales

Basin And Range Topography
Basin and range topography is an alternating landscape of parallel mountain ranges and valleys. It is a result of crustal extension/stretching (extensional tectonics) of the lithosphere (crust and upper mantle) due to mantle upwelling, gravitational collapse, crustal thickening, or relaxation of confining stresses. Crustal extension causes the thinning and deformation of the upper crust in an orientation perpendicular to the direction of extension. As the plates pull apart, they thin allowing the hot mantle to rise close to the surface. When the crust is extended it fractures along a fault plane, creating a series of long parallel normal faults. Between these normal faults are blocks, which subside, get uplifted or tilted. This is known as block faulting. Basins are formed due to subsidence of a block, while the blocks adjacent to the subsidence gets uplifted creating ranges

Salient (geography)
A salient is an elongated protrusion of a geopolitical entity, such as a subnational entity or a sovereign state. While similar to a peninsula in shape, a salient is not surrounded by water on three sides and connected to a geographical mainland. Instead, it is delimited by a land border on at least two sides and extends out from the larger geographical body of the administrative unit. In American English the term panhandle is often used to describe a relatively long and narrow salient, such as the westernmost extension of Oklahoma
