About this map

Yuma Proving Ground dominates this mid-1980s landscape, illustrating the intersection of military operations and the arid Arizona desert. The map tracks the Military Reservation Boundary as it cuts across the southern reach of the Castle Dome Plain and the northern slopes of Red Bluff Mountain. This region is characterized by extensive drainage patterns like Big Eye Wash, which flows southward toward the Mohawk Valley.

Evidence of technical and extractive activity is visible through scattered Prospects, a Gravel Pit, and several Observation Tower sites used for monitoring the range. Transportation and infrastructure in the valley are defined by the Mohawk Canal and the accompanying Road On Levee, alongside remote Landing Strips that supported the specialized needs of the proving ground during this era of Cold War-era testing.
