About this map

Anza-Borrego Desert State Park encompasses a significant portion of this arid landscape, where the San Diego and Imperial County line cuts through the western terrain. The geography is defined by the sharp transition between the Carrizo Badlands and the rising slopes of the Coyote Mountains, which culminate at Carrizo Mtn. This mid-century survey documents a specialized military presence in the northeast via the Carrizo Impact Area Naval Reservation, a site distinct from the surrounding conservation lands.

Travelers and geologists would note the Imperial Highway angling across the southwestern quadrant, passing the Imperial Highway Monument near Carrizo Creek. The presence of a Gravel Pit and scattered prospects suggests the area's small-scale mineral interests. Water is represented by seasonal drainage systems like Fossil Canyon and Palm Canyon Wash, while a lonely Jeep Trail provides the only deep access into the mountain interior.
