Great Basin Divide
Encyclopedia
The Great Basin Divide is the western continental divide
that separates the Great Basin
from the Pacific Ocean
watershed. The water divide
is the perimeter of the largest set of contiguous endorheic watersheds of North America
, including six entire USGS watershed subregions. For example, the San Joaquin River
subregion that drains to the Pacific is adjacent to the Great Basin's Mono-Northern Mojave subregion and central Lahontan subregion, and their triple point is on the Great Basin Divide.
In addition to subregion triple points, the table below lists crossings of various boundaries, including those of states, United States physiographic region
