1955 Map of Poston

About this map

Colorado River Indian Reservation lands dominate this mid-century survey, showcasing a landscape transformed by large-scale irrigation and civic planning. The settlements of Poston and Poston 2 are depicted with their characteristic grid layouts, supported by essential community infrastructure like the Poston School. This area served as the site of a major relocation center during the preceding decade, and by the mid-1950s, the map illustrates the enduring physical imprint of that era through its complex network of water management features, including the Main Drain and numerous irrigation laterals such as Lateral A-73.
