Idaho Springs sits at the northern edge of this high-altitude landscape, where the waters of Clear Creek are channeled through a series of six tunnels along the canyon walls. The terrain is dominated by the massive presence of Santa Fe Mountain and Squaw Mountain, the latter topped with a Radio Relay Station and Lookout. This mid-century survey captures a transition in the local economy, where legacy ranching properties like Evans Ranch Hdqrs and Dodge Ranch Headquarters are mapped alongside the Silver Spruce Mill.
