About this map

The Old Overland Stage Route traces a path through the arid landscape of the Anza-Borrego Desert State Park along the border of San Diego and Imperial counties. This mid-century survey captures the isolation of the Fish Creek Mountains, where the historical Old Carrizo Stage Station sits near Carrizo Creek. The presence of the station and the winding trail reflect the early transportation networks that once bridged these desert basins before modern development.

To the east, the map details the transition into military territory within the Impact Area Naval Reservation. Erosion has carved deep features into the terrain, most notably Red Rock Canyon, Deguynos Canyon, and Barrett Canyon. These washes and canyons, including Split Mountain Wash and Gert Wash, provide a clear picture of the natural drainage systems defining East Mesa and South Mesa during the 1950s.
