Anza-Borrego Desert State Park occupies a significant portion of this late 1950s survey, revealing a landscape defined by seasonal washes and historic desert transit. The Old Overland Stage Route cuts through the terrain, passing the Old Carrizo Stage Sta, a key reminder of the stagecoach era's reliance on reliable water sources like Carrizo Creek. In the southwest, the San Diego and Arizona Eastern Railroad snakes through the Jacumba Mountains, its tunnels and tracks skirting the Volcanic Hills. This era of documentation highlights the transition from early resource extraction to conservation, noting sites like the Dos Cabezas Mine and Montero Quarry alongside the protected groves of the Mountain Palm Springs Area, including Surprise Canyon Grove and Pygmy Grove.
