About this map

Nast serves as the focal point for this high-altitude survey, situated at the confluence of several water systems within the White River National Forest. The landscape is defined by the intersection of natural hydrology and significant water-diversion infrastructure, including the Fryingpan-Arkansaw North Side Collection System, the Nast Tunnel, and the Charles H Boustead Tunnel. These engineering works, along with the Granite Adit, reveal the complex industrial history of water management in the Colorado Rockies.

Local landmarks such as Horseshoe Bend Ranch and Henderson Park are mapped alongside numerous alpine lakes including Ivanhoe Lake, Sellar Lake, and Lyle Lake. The terrain is marked by prominent peaks and passes like Sellar Peak and Hell Gap, while an extensive network of forest roads and historic paths, such as the Savage Lakes Trail 1918.1 and the Sellar Logging Road, provide access through the dense topography near the boundary with San Isabel National Forest.
