About this map

Dillon Reservoir serves as the central focal point of this Summit County landscape, where the waters of the Blue River and Snake River Arm meet. The map reveals the intricate shoreline of the reservoir, including islands like Sentinel Island and Silver Dollar Island, and the modern footprints of Silverthorne, Dillon, and Frisco. Evidence of the region’s massive water-diversion infrastructure is clear with the Harold D Roberts Tunnel and the smaller Old Dillon Reservoir.

Steep elevation gains lead into the White River National Forest, tracing the peaks of the Tenmile Range from Peak One to Peak Five. While the northern section focuses on the reservoir's recreation and suburban development, the southern portion transitions into the industrial and recreational history of the high country. Evidence of mining history remains at Gold Run Gulch, while the modern economy is represented by the extensive trails of the Breckenridge Ski Area and the local Frisco - Keystone Bikepath.
