1969 Map of Columbia

USGS Topo · Published 1973

About this map

Bradshaw Mountains mineral wealth is evident throughout this late 1960s survey, centered on the settlement of Columbia. The landscape is a network of industrial sites and small claims, including the Red Star Mine, Pero Bonito Mine, and the Hardtimes Mine Ruins. The presence of Allen Mill and the Gold Spring Mine suggests a localized economy built on extraction, supported by isolated outposts like Milk Ranch and Champie Ranch.
