1939 Map of Borrego

USGS Topo · Published 1956

About this map

Anza Desert State Park and Borrego State Park dominate this 1939 aerial survey, revealing the early infrastructure of the San Diego backcountry. The landscape is defined by the convergence of steep ranges like the Vallecito Mountains and the Pinyon Mountains with broad, arid basins such as Earthquake Valley. The presence of the Overland Stage Route trailing through Blair Valley provides a clear link to the region's mid-19th-century transit history, showing the path taken by travelers long before modern highways.
