Location and Description

This 7,880-acre wilderness lies 40 miles south of Colorado City, Arizona, just north of the Grand Canyon in Mohave County.

Located at the southern end of the Uinkaret Plateau and part of the Uinkaret Mountains, Mt. Trumbull is a large, basalt-capped mesa with slopes dominated by pinyon pine and juniper trees interspersed with groves of aspen and Gambel oak. The summit or the plateau is covered with ponderosa pine. These vegetation communities provide homes for mule deer, wild turkey, and the Kaibab squirrel.

Recreation opportunities include day hiking, watching and hunting wildlife, and photography.
