1956 Map of Spinney Mountain

USGS Topo · Published 1958

About this map

The South Platte River winds through the high-altitude landscape of Park County in the mid-1950s, feeding into the expansive Elevenmile Canyon Reservoir. This survey highlights the region's ranching heritage, specifically detailing the Hartsel Ranch (Lower Spinney Unit) and the Hartsel Ranch (Rogers Unit), which sit at the base of Spinney Mtn. A significant piece of transportation history is visible in the Old Railroad Grade, tracing a defunct path through the river valley west of the reservoir. The map documents an environment shaped by water management and grazing, with numerous drainages like Threemile Creek, Pruden Creek, and Boyer Gulch cutting through the foothills. Portions of the Pike National Forest flank the eastern and southern edges, anchored by the prominent Stoll Mountain. Local transit is represented by the winding Thirtynine Mile Road, which provides access to the rugged southeastern terrain.
