About this map

Observatory Rock stands as a prominent landmark in this high-elevation landscape within the Pike National Forest, where late 1950s ranching operations and early settlement sites are meticulously documented. The map details a network of family-held properties including Ingram Ranch, Johnston Ranch, and Miller Ranch, illustrating the dispersed pastoral economy of the era. A significant historical anchor is found at the Bordenville (Site), where the Bordenville Cem and a nearby Schoolhouse mark the remains of a once-active community hub along Tarryall Creek.

The drainage patterns of Michigan Creek and Hall Gulch define the topography, supporting numerous water sources like Robbins Spring and Dixon Spring that were vital for livestock at the Rock Creek Cow Camp. Travel through this territory is centered on the Lost Park Road, providing a glimpse into the seasonal migration and land use of Colorado’s high country before modern development altered these remote ranching corridors.
