1979 Map of Sylvan Reservoir

About this map

Arapaho National Forest dominates this landscape, showing a complex network of drainages and high-elevation parks in the late 1970s. The hydrology of the area is defined by the convergence of numerous named streams, including Little Muddy Creek, Kelly Creek, and Keyser Creek, which carve through deep gulches like Sylvan Gulch and Morgan Gulch. Human infrastructure is sparse but significant, centered on water management and forest service operations. The Sylvan Reservoir and De Koevend Lake appear as key water bodies, while the Horseshoe Guard Station provides a central landmark for wilderness management. Evident industrial activity is concentrated near Ute Park in the south, where Gravel Pits and a Tailings Pond indicate the localized extraction and processing of materials. Higher elevations are marked by the prominent Blue Ridge and the open spaces of Brinker Park.
