About this map

Mining operations dominate the landscape of Big Gypsum Valley and the surrounding canyons in this Colorado survey. Dozens of active and historic claims are scattered across the high terrain, including the Sunday Mine, West Sunday Mine, and the Saint Jude Mine. The density of these sites, particularly around Hamm Canyon and the Big Gypsum Creek drainage, reflects a legacy of uranium and vanadium extraction that shaped the local economy.

Water sources like the Dolores River and Disappointment Creek carve through the sedimentary layers, creating prominent landmarks such as Cape Horn. Road networks like s22 RD provide access to these remote reaches, connecting operations like the Uncle Sam Mine and Old Mexico Mine to the broader region. This document serves as a detailed record of industrial footprints in San Miguel County just after the turn of the twenty-first century.
