"The Desert Southwest is exactly what it sounds like: Desert.. The arid regions of Nevada, Arizona, and New Mexico predominate, with their rocky peaks. The major vegetation in these areas consists of desert scrub and cacti. Rainfall in this region is sporadic, limited to annual downpours that lead to flash floods. Habitation is sparse and centers around water and/or major highways. Some towns are little more than wider parts in the road with gas stations. A quarter tank of gas can mean the difference between life and death here.

The southern half of the state is similar to the more arid areas of Utah and Arizona, while the Northern and coastal regions are more lush and green, like Colorado."@en . .
