Galiuro Wilderness
The precipitous, rocky, and brushy Galiuro Mountains rise abruptly in block-like uplifts from the almost flat desert plains. Nineteen miles in length and six miles in width (on average), they are almost all designated Wilderness. Erosion has done its work here, creating many rugged cliffs with brightly colored rocks and exposed soils. Bisected by two main canyons, Redfield and Rattlesnake, the mountains support vegetation varying from semidesert grasslands through pinion, juniper, oak, and brush to mixed conifers and even aspens in the higher elevations. From about 4,000 feet, the ground rises to 7,671 feet on Bassett Peak. You'll find no perennial streams, but riparian areas appear throughout the Wilderness.
