About this map

The Old Overland Stage Route cuts across the southern portion of this desert landscape, tracing a historical path through the arid lowlands of Imperial and San Diego counties. This transit corridor anchors the map at the Old Carrizo Stage Station, a vital stop for nineteenth-century travelers navigating the Colorado Desert. The geography is defined by a sharp contrast between the jagged Carrizo Mountains and the flat expanses of East Mesa and South Mesa.

Military and conservation interests overlap here, as seen in the boundary between the Anza-Borrego Desert State Park and the Impact Area Naval Reservation. Seasonal drainages like Fish Creek, Carrizo Creek, and Deguynos Canyon reveal the erosive forces that have shaped landmarks like Split Mountain. Surveyors also noted high-altitude markers such as BM 2371 Eagle and VABM 767 Gert, providing essential data for this mid-century topographic record.
