Mount Signal and the surrounding borderlands of the Imperial Valley are defined by a complex network of irrigation and drainage infrastructure designed to manage the arid landscape. The New River meanders across the northern portion of the map near Wulfs Crossing, while the southern reaches are dominated by engineered waterways like the Worm Wood Canal and Woodbine Canal. To the west, the landscape transitions into the open expanse of West Mesa, away from the grid-patterned agricultural fields. This system of laterals and drains, including Wistara Canal and Fern Side Main, illustrates the intensive hydrological engineering required to sustain cultivation along the California-Mexico border. The alignment of roads such as Westside Rd and Signal Rd follows these water features, anchoring the rural settlement pattern to the valley's artificial water supply.
