1956 Map of Spinney Mountain

USGS Topo · Published 1985

About this map

The South Platte River winds through this high-altitude landscape, feeding into the massive Elevenmile Canyon Reservoir and the smaller Spinney Mountain Reservoir. This mid-century survey, with revisions from the 1980s, documents a transition from traditional ranching lands to recreational water management. The prominent presence of the Hartsel Ranch (Lower Spinney Unit) and Hartsel Ranch (Rogers Unit) highlights the area's agricultural roots, while the Elevenmile Canyon State Recreation Area points toward its modern utility. Transportation history is visible in the Old Railroad Grade that skirts the riverbank, and the Aqueduct near the southern boundary reveals the complex engineering required to manage mountain water resources. The terrain is framed by high points like Stoll Mountain and Spinney Mtn, with much of the eastern and southern portions falling within the Pike National Forest.
