Sonoran Desert National Monument in Arizona is a magnificent example of untrammeled desert. Within one of the most biologically diverse North American deserts, the most striking aspect of the monument’s plant community is the extensive saguaro cactus forest. The monument also contains three mountain ranges all separated by wide valleys. Visitors can explore wilderness areas and remnants of several important historic trails and have all the fun under the sun. Photo by Bob Wick, Bureau of Land Management.
