The Sonoran Desert National Monument contains more than 487,000 acres of Sonoran Desert landscape. The Sonoran Desert is the most biologically diverse of the North American deserts, and the monument exemplifies this desert setting. 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 is also home to three congressionally designated wilderness areas, many significant archaeological and historic sites, and remnants of several important historic trails.
