Stable numbers of Coues deer live in the high parts of three mountain ranges—Sierrita, Cerro Colorado and Las Guijas. Desert mule deer live in the low, rolling foothills and Sonoran desert flats and valleys. Illegal immigrants often travel through this unit, so make sure vehicles and campsites are secure.

This unit has both Coues deer and desert mule deer. Be prepared to encounter Border Patrol agents and illegal immigrants. There is good access despite a great deal of private land.
