Anza-Borrego Desert State Park dominates this late-1950s survey, revealing a landscape defined by complex desert drainages and mesa formations in eastern San Diego County. The transport network is anchored by historical transit corridors, most notably the Old Overland Stage Road and the Old Overland Stage Route, which weave through the arid terrain near the Tierra Blanca Mountains. These routes pass vital watering points and natural landmarks like Mesquite Oasis, Palm Spring, and the curiously named Well of the Eight Echoes in the Carrizo Valley.
