The Great Basin ( English Great Basin ) is a dry bulk landscape that stretches to the west of the United States between the Wasatch Range to the east and the Sierra Nevada and Cascade Range to the west across several US states , but mostly in Nevada , covers. Oregon , Idaho , Utah , Arizona and California also have smaller shares . The boundaries of the Great Basin are defined differently: The Great Basin is generally understood to mean the areas that form a drainage-free catchment area . The Great Basin Desert is understood to mean the areas in which the characteristic vegetation of the Great Basin predominates. Basin and Range is a geological region that is much larger than the actual basin and also includes the Mojave and Sonoran Deserts in Mexico .

Also one of the North American cultural complexes of the indigenous population is Great Basin ( Great Basin called).

Classification

The large basin consists of around 100 partial basins or valleys in which there are numerous “mountain islands”. It is of steppe-like areas, stone and sand desert thunderstorm lying Bach - and rivers , canyons , salt lakes and pans and some small and large lakes (eg Great Salt Lake , Utah Lake and Pyramid Lake ) coined. In the north of the Great Basin runs the Humboldt River , which ends in the west under the flank of the Sierra Nevada in small lakes with no drainage, in which the water evaporates in the desert air.

The valleys or sub-basins that form their own drainage-free catchment areas are:

history

While the lower rock layers come from the Archean , the surface shape of the Great Basin is only about 17 million years old.

Due to a surveying error in the Great Basin region, it was believed until the 1840s that a river called the Buenaventura River connected the Great Salt Lake with the Pacific.
