Ground Automotive Proving grounds dominate the northwest corner of this 1970s desert landscape, reflecting the military and industrial utility of the Arizona backcountry. The terrain is defined by a series of wide, episodic drainage systems including Mackenzie Wash and Alamo Wash which cut across the alluvial fans of Dutch Flat. Resource extraction is a primary theme of the era, anchored by the presence of the Boriana Mine in the north and various prospects and drill holes scattered through the basin. Connectivity across this arid expanse is maintained by the Alamo Road and a remote Landing Strip, providing essential access for the ranching and mining operations that once operated beneath landmarks like Cactus Mtn and the isolated rise of Flattop.
