High-altitude silver and gold mining dominates this 1904 survey of the San Juan Mountains, centered on the bustling industrial hub of Telluride and the nearby milling center of Pandora. The landscape is a dense network of extraction, with legendary operations like the Smuggler Mine, Sheridan Mine, and Virginius Mine clinging to the steep basins above the San Miguel River. This era represents the peak of the region's vertical economy, where heavy machinery and ore were moved via the Rio Grande Southern R.R. through critical transit points like Vance Junction and Ophir Sta.
