1994 Map of Homestake Reservoir

About this map

Turquoise Lake and the Homestake Reservoir dominate this high-altitude landscape along the Continental Divide, where the borders of Eagle, Pitkin, and Lake counties converge. The map documents a complex network of water management and industrial history, evidenced by a high density of subterranean infrastructure. Numerous engineering feats are marked, including the Hagerman Tunnel, Canlton Tunnel, and the Boustead Tunnel, which pierce the mountain ridges to move water and rail traffic. To the east, the legacy of Colorado's mining era is visible through a concentration of named shafts and adits such as the Saint Kevin Shaft, Dinero Tunnel, and the Homestake Mine. These workings sit nestled between prominent peaks like Homestake Peak and Sugarloaf Mountain, illustrating the intense search for mineral wealth in the rugged terrain of the Holy Cross Wilderness and San Isabel National Forest.
