1958 Map of Observatory Rock

USGS Topo · Published 1991

About this map

The ghost town of Bordenville serves as a central historical marker in this landscape, situated along the banks of Tarryall Creek. This mid-century survey captures the remote ranching character of Park County, where family holdings like the Miller Ranch, Johnston Ranch, and Coleman Ranch are connected by a network of gulches and springs. The terrain is dominated by the Pike National Forest and the Lost Creek Wilderness, protecting a complex geography of granite outcrops and narrow drainages. Notable landmarks such as Observatory Rock and Mud Hill overlook the valley floor, while the Bordenville Cem remains as a tangible link to the area's early settlement history. The map also traces established transportation routes like the Lost Park Road, providing a detailed look at the water sources—from Lone Chimney Spring to Porcupine Spring—that were vital for high-altitude ranching and survival in the Colorado front range.
