Imperial Valley terrain meets the shoreline of the Salton Sea in this topographical study of the southern California desert. The landscape is defined by the stark transition from the water's edge to the elevated formations of the Bat Caves Buttes. Historical transit and utility corridors are prominent, with Grapefruit Blvd and several rail-adjacent settlements like Durmid, Bertram, and Ferrum following the low-lying basin.
