1958 Map of Observatory Rock

About this map

Tarryall Creek and Michigan Creek converge in this high-altitude landscape within the Pike National Forest, where late-1950s land use is defined by isolated ranches and rugged gulches. The settlement of Bordenville (Site) is recorded here, including the Bordenville Cem, indicating a community that once served this mountain valley. Family names are tied to the terrain through several working spreads, such as Ingram Ranch, Miller Ranch, and Highfill Ranch, while more temporary operations like the Rock Creek Cow Camp appear near the Beaver Ponds. The prominent Observatory Rock stands as a primary landmark above Swiggler Gulch, overlooking a network of jeep trails and historic paths like the Lost Park Road that navigated the basin before modern development reached this part of the Front Range.
