Long considered a top-quality destination for hunting desert bighorn sheep, this unit stretches from 30-120 miles west of Phoenix. Desert flatlands separated by washes and small, rocky mountain ranges hold a good number of sheep as well as a few quality mule deer.

Unit 41 produces some of the biggest mule deer in southwestern Arizona. Hunters who draw sheep tags for hunting in either subunit have a chance to take mature desert bighorn rams.

Most of the unit is flat desert land with heavily vegetated riparian drainages. Several rough and barren mountain ranges rise from the desert. The western edge borders Kofa Refuge Wilderness, and the eastern tip is near Valencia/Buckeye about 30 miles west of the center of Phoenix.

Flatlands are mostly barren but support creosote, ironwood, paloverde and saguaro cactus. The mountains have creosote and palo verde. Riparian washes are heavily vegetated in places.

Most of the unit is open to public hunting and is managed by the BLM and the state. Some low-elevation private land is developed or agricultural and limits access to some public ground.

Most hunters camp along dirt roads on BLM and state property. Lodging and services are in Gila Bend, Wellton and Yuma. Commercial RV parks are in Yuma and Wellton.
