1956 Map of Mount Callaghan

About this map

Mount Callaghan dominates this mid-century high-desert landscape, where ranching and rugged relief define the territory. The map centers on the transition between the Shoshone Range and the sprawling Grass Valley, which is dotted with isolated homesteads and working livestock operations. Several family-named properties like Callaghan Ranch and Grass Valley Ranch are connected by a network of unimproved roads and a jeep trail that navigate the drainages of Skull Creek and Silver Creek. A small Landing Field near the Grass Valley Ranch indicates the scale of travel required in this secluded region during the 1950s.
