The Santa Rosa Mountains dominate this high-desert landscape along the border between Riverside Co and San Diego Co. The terrain is defined by steep, arid drainage systems, including the deep Martinez Canyon in the north and Rockhouse Canyon to the southwest. These geological features reveal a complex network of dry washes and canyons that terminate in the broad, flat expanse of Clark Valley.
