The Imperial Valley landscape meets the southwestern shore of the Salton Sea in this topographical survey, showing a region defined by its desert water management and distinctive geology. Agricultural infrastructure is dense in the northeast corner, where a network of irrigation channels like the Trifolium Extension, Barth Lateral, and Lateral Number One divert water into the low-lying basin. This highly engineered hydrological system contrasts sharply with the arid terrain of the Superstition Hills to the south.
