The Southern Pacific railroad corridor anchors this 1901 survey, tracing the low-lying basin through Indio, Coachella, and Thermal. This era captures the landscape before modern irrigation transformed the valley, showing early settlements like Mecca and Mortmar situated well below sea level as they follow the rail line toward the Salton Basin. To the west, the topography rises sharply into the San Bernardino National Forest and the Santa Rosa Mountains, where resource extraction is marked by the Asbestos Mine and the Garnet Queen Mine. Cultural geography is preserved through the extensive boundaries of the Toro Indian Reservation and smaller holdings like the Augustin Indian Res. Researchers can find early desert outposts and watering holes such as Indian Well, Agua Dulce, and Figtree John that once served as vital stops in this arid terrain.
