1965 Map of Castle Dome Mts

About this map

The Castle Dome Mountains dominate this mid-1960s landscape, serving as a backdrop for a desert economy defined by isolated mining claims and water management. To the west, the Yuma Proving Ground creates a sharp administrative boundary across the La Posa Plain, while the interior of the range is dotted with significant mining sites such as the Hull Mine, Colorado Mine, and Keystone Mine. The presence of the Colorado Mine Cem near these workings highlights the permanence of these remote outposts during their operational years.
