1971 Map of Moon Mtn NE

About this map

Mesquite Mountain dominates the central landscape of this western Arizona quadrangle, creating a stark topographical divide between the lowlands of Parker Valley to the west and the expansive La Posa Plain to the east. The 1971 survey captures the area at a time of early industrial activity and complex land management, evidenced by the prominent Colorado River Indian Reservation Boundary slicing through the terrain. In the western portion of the map, resource extraction is visible through several clusters of Gravel Pits and a solitary Gravel Pit, providing a specific look at the mid-century infrastructure and land use in this desert environment. The map details the transition from high-relief mountain ridges to the broad alluvial plains of the La Posa Plain.
