 The outer boundaries encompass approximately 496,337 acres. The monument contains magnificent examples of untrammeled Sonoran Desert landscape. The Sonoran Desert is the most biologically diverse of the North American deserts, and the monument captures a significant portion of that diversity. The most striking aspect of the plant community within the monument is the extensive saguaro cactus forest. The monument contains three distinct mountain ranges, the Maricopa, Sand Tank and Table Top Mountains, as well as the Booth and White Hills, all separated by wide valleys. The monument also contains three Congressionally designated wilderness areas and many significant archaeological and historic sites, and remnants of several important historic trails. This area provides numerous opportunities to learn about prehistoric and historic sites. Additional activities include wildlife viewing, camping, hiking, hunting and back-country vehicle travel. Off highway vehicle use is prohibited. No motorized and mechanized use of vehicles and equipment is allowed in wilderness.
