1958 Map of Observatory Rock

About this map

Bordenville serves as a focal point for this mid-century look at the eastern edge of South Park, situated where Tarryall Creek winds through the valley. The map documents a landscape defined by ranching and high-altitude grazing, featuring the Ingram Ranch, Miller Ranch, and the Rock Creek Cow Camp at the edge of the Pike National Forest. This 1950s survey preserves the location of the Bordenville Cem and various family-named holdings like Johnston Ranch and Highfill Ranch, many of which were accessed by the winding Lost Park Road. A labyrinth of named drainage channels, including Graveyard Gulch and Schoolhouse Gulch, illustrates the complex hydrology of the watershed beneath the prominent geological landmark of Observatory Rock. The area remains sparsely populated, with the layout of these gulches and springs providing critical context for the region's historic ranching boundaries.
