The Animas River corridor and the high mountain basins of the San Juan National Forest define this 1960 field-checked survey. Central to the landscape is the expansive Electra Lake, flanked by smaller alpine waters such as Ignacio Lake, Papoose Lake, and Aspaas Lake. The rugged geography is marked by the towering Hermosa Cliffs to the west and the West Needle Mountains to the northeast, creating a dramatic vertical relief that dictated early transportation routes.
