1951 Map of Sheep Mountain

About this map

Sheep Mountain and the high ridge of Tatman Mountain dominate this mid-century landscape in the Big Horn Basin. The survey highlights a rugged topography where drainage systems like Dry Cottonwood Creek and Rock Waterhole Creek carve through the arid terrain. Human intervention in this environment is clearly marked by the infrastructure of the St Joe Canal and various irrigation features, including Neres Reservoir and Dobson Pond. These water management systems reflect the critical efforts to support life and agriculture in Wyoming's high plains during the early 1950s. The map provides a precise record of the complex network of unnamed trails and unimproved roads that connected these remote water sources and high-elevation points, serving as an essential resource for tracing the historical land use and hydrologic development of the region before modern expansion.
