1956 Map of Antero Reservoir NE

USGS Topo · Published 1986

About this map

The South Fork South Platte River winds through this high-altitude Park County landscape, revealing a transition from active ranching to a quieter rural era by the mid-1950s. While Poyner Ranch remains a central landmark, the map records a high concentration of sites no longer in active use, such as Weber Ranch, Jamestown Ranch, and Oakley Ranch. These markers, alongside the Pleasant Valley Sch, suggest a once-larger community of homesteaders and ranchers supported by the local water network. Transportation history is clearly visible through the Old Railroad Grade and an Abandoned Ditch, while natural water sources like Antelope Spring and Agate Creek continue to define the drainage patterns of this mountain basin. The topography captures the basin floor before significant modern development, preserving the footprint of early South Park cattle operations and transit routes.
