Anza-Borrego Desert State Park dominates this mid-century landscape, revealing a complex network of canyons and high desert ridges. The map emphasizes the historical significance of the Old Overland Stage Route as it cuts through Earthquake Valley and Vallecito Valley, passing the San Felipe-Butterfield Stage Station Historical Marker at Scissors Crossing. This corridor was vital for southern transcontinental travel, following the natural breaks in the Pinyon Mountains and Chuckwalla Mountains.
