Mining operations and sophisticated irrigation networks define the rugged drainage basins of the La Plata River and its tributaries in this 2011 topographic record. The landscape is heavily marked by its mineral history, with a high concentration of sites like the May Day Mine, Inca Claims, and Western View Mining Group Mine clustered near Mayday. These sites illustrate the intensive prospecting that occurred throughout the canyons of the San Juan foothills. Downstream, the small settlement of Hesperus sits near the Hesperus Cemetery, serving as a focal point for the region’s development.
