North Maricopa Mountains Wilderness

The North Maricopa Mountains Wilderness consists of a series of rocky, isolated summits, long ridges, and vast, level valley floors. The ridges are dissected by normally dry washes and separated by desert outwash slopes (bajadas). Elevations in this Wilderness range from approximately 900 feet, near Gila Bend, to approximately 3,000 feet, at Butterfield Pass. The two major vegetation communities which characterize this area include Paloverde-Mixed Cactii, which consists of dense "forests" of saguaro cactus, paloverde, and ironwood, and Creosote-Bursage, which covers low elevation valley floors in seemingly unbroken expanses.
