1967 Map of Union Pass

USGS Topo · Published 1985

About this map

Mining operations and rugged desert terrain define this mid-century portrait of the Black Mountains in Mohave County. In the late 1960s, the landscape was a network of resource extraction and transit, anchored by the Tyro Mine and the Arabian Mine. The historic Union Pass serves as a primary corridor through the high country, where old Telephone lines and a Jeep Trail trace the movements of prospectors and surveyors.
