About this map

Barnum serves as a central point in this ranching landscape of the southern Big Horn Mountains, where the high plains meet the eastern slopes. The settlement and surrounding homesteads like Graves Ranch and Wolcott Ranch rely on an intricate network of irrigation channels, including the Winsor Ditch, White Panther Ditch, and Barnum Ditch, which divert water from the Beaver Creek and Blue Creek. This complex water-management system illustrates the adaptation required for agriculture in Johnson County's arid environment.

Prominent geographical features such as Poison Weed Ridge, Telephone Ridge, and Buckbrush Butte dominate the western half of the map, while the Red Fork Powder River and Middle-Fork Powder River carve through the eastern terrain. The presence of naming conventions like Horse Pasture Ridge and Sawmill V Ridge reflects the historical land use patterns of early 21st-century Wyoming ranchers and land managers.
