2014 Map of Poston

About this map

Parker Valley agriculture defines the landscape of this region along the border of Arizona and California. The community of Poston sits at the northern edge of a complex irrigation network, where engineered waterways like Lateral Number Seventy-nine, the Leupp Lateral, and Mesa Drain distribute water across the desert flats. This intricate system of laterals and drains follows a rigid grid of roads, including Mohave Dr and Navajo Rd, reflecting the methodical development of the valley for cultivation. To the northwest, the Colorado River meanders past the Riverside Mountains, providing the lifeblood for the surrounding fields. The map documents a strictly organized rural landscape, where residential clusters like Poston are deeply integrated into the hydraulic infrastructure that makes settlement possible in the arid Southwest.
