About this map

The Old Overland Stage Route winds through the arid landscape of the Colorado Desert, marking a path of significant historical transit across the San Diego and Imperial County line. This mid-century survey highlights the Old Carrizo Stage Station, a critical waypoint for travelers during the era of stagecoach travel. The terrain is defined by dry watercourses such as Carrizo Wash and Split Mountain Wash, which drain the eastern slopes of the Fish Creek Mountains.

Military and conservation boundaries dominate the land use on this sheet. Much of the western portion is dedicated to the Anza-Borrego Desert State Park, while the eastern section is marked as a Naval Reservation, including a designated Impact Area. The transition from the high elevations of East Mesa and South Mesa into deeply cut features like Deguynos Canyon illustrates the stark geological character of this region during the 1950s.
