About this map

Silverthorne and Dillon serve as the primary hubs in this high-elevation landscape, where the Blue River valley meets the expansive Dillon Reservoir. The map reveals a complex interface between residential development and the steep terrain of the Gore and Williams Fork ranges, marked by landmarks like Tenderfoot Mountain and Ptarmigan Peak. Transportation corridors follow the natural topography, with modern road networks such as Ruby Ranch Rd and Hamilton Creek Rd branching into the foothills.

Evidence of the region's industrial and recreational history is present through features like the Skookum Mine and the Dillon Forest Service Facility. Significant water systems define the geography, from the Blue River Ranch Lakes to the numerous drainages including Straight Creek and North Willow Creek. This 2011 survey captures a moment of modern growth while maintaining clear records of the mountain passes and gulches, such as Ptarmigan Pass and Laskey Gulch, that have long dictated movement through this part of Colorado.
