Land Cover of California & Great Basin Fine Art Print Map
The Great Basin, as defined by interior drainage never reaching the sea,
occupies most of Southeastern California, as well as a lot of Oregon,
and most of Nevada and western Utah. Large neighboring areas share the same characteristic climate, dominant landforms, and bioregion, despite
streams connecting to the Columbia-Snake or Colorado systems.
geologically recent and still rising Cascades and Sierra Nevada create
the rain/snow shadow that, together with its overall mountainous
character, is the determining influence over the whole region. The Salt Lake Basin is the largest of the many sub-basins, many already
entirely dry after long periods as snow- and glacial-meltwater lakes.
Included on the map are all of
California and Nevada, almost all of Utah and Arizona, half of Oregon and
Idaho, some of Montana and Wyoming, along with smaller portions of New Mexico,
Baja California, and Sonora.
