Salton Sea dominates the northeast corner of this Imperial County landscape, its water surface recorded at 241 feet below sea level during this wartime survey. The shoreline includes Sea View Beach and Sandy Beach, both situated within a large Migratory Bird Refuge. Inland, the desert terrain is defined by the Superstition Hills and the arid expanse of West Mesa, where resource exploration is evidenced by the Diamond Bar Test Well and Mesquite Drill Hole.
