Yuma Desert

Human presence is sparse throughout; the largest city is Yuma, Arizona, on the Colorado River and the border of California.

The desert includes the lower-elevation parts of the southwestern corner of Arizona, extending west to the Colorado River.

[citation needed] The Yuma Desert also includes the sandy plains of western Sonora, going all the way to the head of the Gulf of California, then an inland strip reaching into the central Sonoran interior.

[citation needed] The name Yuma desert has been in use since at least the 1929 geological mapping survey conducted by Eldred D. Wilson for the Arizona Bureau of Mines.

The Yuma desert is the northern edge of the distributions of the elephant tree (Bursera microphylla)[2] and the blue Baja lily (Triteleiopsis palmeri).
