2013 Map of Dillon

About this map

Silverthorne and Dillon sit at the confluence of the Blue River and Straight Creek, serving as a modern nexus of recreation and infrastructure. The landscape is defined by the high elevations of the Williams Fork Mountains and the massive basin of the Dillon Reservoir to the south. This 2013 survey illustrates the dense network of residential development stretching from the banks of the reservoir up into the foothills, particularly around Blue River Ranch Lakes and the neighborhoods near Willow Creek. The map documents a heavily managed wilderness, where the Arapaho National Forest and White River National Forest are accessed through an extensive system of trails like the Ute Peak Trail 24 and Ptarmigan Loop Trail 69.1, which trace the high ridges and glacial valleys such as Laskey Gulch.
