The Kofa National Wildlife Refuge and the northern reaches of the Yuma Proving Ground meet in this 1980s topographic study of the Arizona desert. The landscape is defined by the sharp transition between the elevated Kofa Mountains and the sweeping Castle Dome Plain. Human activity in this arid environment is recorded through a network of Mine Shaft and Prospects labels, marking the region's history of mineral exploration near Natural Arch.
