The international border between the United States of America and Mexico anchors the southern edge of this survey, where the irrigation-dependent landscape of the Imperial Valley meets the high desert of the East Mesa. The settlement at Bonds Corner serves as a small hub amidst a complex network of water management, defined by the Whitcomb Canal, Hemlock Canal, and Holt Canal. This infrastructure transformed the arid terrain into a productive agricultural zone, evidenced by the dense grid of lateral drains such as Bonds Corner Drain Six and Verde Drain.
