The San Miguel River carves a deep valley through the high country of the Uncompahgre National Forest, revealing a landscape shaped by early mountain industry and transportation. Tiny settlements like Saw Pit, Vanadium, and Ilium dot the riverbanks, marking the sites of former mining and milling operations. This 1953 field-checked survey, produced in cooperation with the Atomic Energy Commission, highlights the region's mineral importance, though notes that features like the Belle Champion Mine were inactive at the time of mapping.
