About this map

The Granite Mountains dominate this high-desert landscape in central Wyoming, where the Sweetwater River carves a path through distinctive geological formations. A clear picture of mid-century ranching life emerges through the locations of the McIntosh Ranch, Hat Ranch, and Split Rock Ranch, which anchor the irrigation-dependent valley. The presence of the Split Rock School and landmarks like the Great Stone Face suggest a small but established community centered around the river corridor.

Evidence of changing land use is visible in the abandoned sites marking the terrain, including the CCC Camp (Aband), the Grieves Homestead (Aband), and the Speyers Reservoir (Aband). Infrastructure like the McIntosh Ditch and the Beaton Ditch illustrate the engineering required to sustain these remote holdings. From the heights of Telephone Ridge to the namesake notch at Split Rock, the map documents a territory defined by hard-won water rights and early 20th-century frontier settlement patterns.
