2011 Map of Thimble Rock

About this map

Smuggler Mountain and the high ridges of the Sawatch Range define this landscape, where mining infrastructure and water management systems reflect the region's industrial heritage. The Tower Durant Tunnel Mine and the significant Hunter Tunnel demonstrate the extensive subsurface engineering required to extract resources from these heights. The map details a complex hydrologic network feeding into the Roaring Fork River, including Warren Lakes and the Warren Lake Dam. Elevated basins such as Deer Park, Horse Park, and Slab Park are interspersed between prominent landmarks like Thimble Rock and Bald Knob. This 2011 survey captures the area's high-altitude geography, from the crossing at Midway Pass to the alpine waters of Sawyer Lake and Midway Lake, providing a clear view of the terrain before more recent environmental shifts.
