2016 Map of Keystone

About this map

Keystone serves as the central hub of this mountain landscape, which is defined by a dense network of recreational paths and infrastructure engineered for water diversion. The massive Harold D Roberts Tunnel cuts through the northern terrain, a significant feat of civil engineering designed to carry water under the Continental Mountains. While the modern Keystone Ski Area and Frisco - Keystone Bikepath indicate the region's contemporary use, older industrial traces remain in the landscape, such as the Soda Mine and the Hunkidori Mine Trail. The southern portion of the map is dominated by the headwaters of the Swan River and its various branches, including the N Swan River and Fork Swan River, which carve through deep gulches like Galena Gulch and Garibaldi Gulch. This 2016 survey illustrates the layered history of the area, from early prospecting at Brewery Hill to its current role within the White River National Forest.
