This unit, mostly on the Yuma Proving Grounds east of the Colorado River, has a stable herd of desert bighorn sheep and some mule deer. Reports show that over three years, all hunters have taken rams scoring an average of 160" B&C.

Hunters have an excellent opportunity to take a trophy desert bighorn. Mule deer numbers are low but slightly increasing with big, mature bucks residing in desert flatlands. There is also excellent wingshooting available for dove, quail and waterfowl.
