Gila Lower Box Wilderness Study Area

An oasis in the desert, the Gila Lower Box WSA is located in southwestern New Mexico about 20 miles northwest of Lordsburg. The Gila River has cut a five mile-long steep-walled canyon 600 feet deep in some areas, creating the "Lower Box." The pristine canyon is heavily vegetated with riparian species such as ash, cottonwood, Arizona sycamore, and willow. The Lower Box has very high biological diversity with 265 species of birds, 67 mammal species, 12 species of amphibians, and 54 reptile species recorded. This is one of the best bird watching areas in New Mexico. The area contains cultural features including petroglyphs and rock shelters.
