About this map

The Continental Divide serves as the backbone of this high-altitude landscape, where the headwaters of the Homestake Creek and West Tennessee Creek drain through the White River National Forest and San Isabel National Forest. This 1970 field-checked survey reveals an intricate network of industrial sub-surface engineering, dominated by several major bores including the Hagerman Tunnel, Carlton Tunnel, and the Charles H Boustead Tunnel. These engineering feats, along with the Busk-Ivanhoe Tunnel, illustrate the complex water diversion and transport history required to move resources across the divide.

Evidence of the region's mining and transit legacy is visible along the Old RR Grade winding toward Hagerman Pass. Heavy mineral exploration is documented through several named vertical workings such as the St Kevin Shaft, Grandview Shaft, and Tiger Shaft. The landscape is further defined by substantial reservoirs like Homestake Reservoir and Turquoise Lake, which sit amidst prominent peaks like Homestake Peak and Sugarloaf Mountain.
