2017 Map of Sheep Mountain

About this map

Sheep Mtn and Tatman Mtn dominate this portion of Big Horn County, defining a landscape shaped by significant topographic relief and a network of seasonal drainages. The map reveals the intricate management of water in this arid environment through features like the Saint Joe Canal and man-made catchments such as Neves Reservoir and Dobson Pond. These developments indicate the essential role of irrigation and water storage for supporting life and land use in the Big Horn Basin. Numerous named watercourses, including Dry Cottonwood Cr and Rock Waterhole Cr, carve through the terrain, illustrating the natural drainage patterns that have dictated local ranching and transit routes for generations. This 2017 survey by the U.S. Geological Survey provides a precise view of the physical geography and public land survey system grid across townships like T50N R97W.
