1960 Map of Hamm Canyon

USGS Topo · Published 1961

About this map

The Dolores River winds through the western edge of this 1960 survey, cutting a path through the sandstone canyons of San Miguel County. The landscape is defined by the significant geological basins of Gypsum Valley and Disappointment Valley, which dominate the central and southern portions of the sheet. Between these valleys, a network of uranium and vanadium exploration is evident, marked by numerous small-scale mining operations including the Chile No 5 Mine, Mexico Mines, and the Sunday No 2 Mine. These claims follow the mineral-rich strata above Big Gypsum Creek, illustrating the era's intensive resource extraction. Distinctive landforms such as Cape Horn and Hamm Canyon overlook the tributary waters of Nicholas Wash and Mary Jane Draw, providing a detailed look at the drainage patterns before these remote drainages join Disappointment Creek.
