Imperial Valley irrigation infrastructure dominates this 2015 survey, revealing the intricate network of canals and drains that support agriculture in the desert southeast of the Salton Sea. The settlement of Westmorland sits at the eastern edge, while the northern extent shows the New River delta as it enters the sea. The landscape is a geometric grid of water management features, including the Tokay Canal, Thistle Canal, and dozens of numbered laterals like Trifolium Lateral Twelve. This system illustrates the engineered hydrology required to sustain the region, with the New River cutting through the center of the valley.
