About this map

Sunshine Reservoir dominates this high-plains landscape, serving as a critical water management hub in the Upper Sunshine Basin. This 2021 survey illustrates a sophisticated network of irrigation infrastructure essential for local agriculture, including the Sunshine Supply Ditch, Pappapau Ditch, and the curiously named Only Chance Ditch. These man-made channels draw from the Greybull River and Wood River to transform the arid basin floor.

To the southwest, the terrain rises sharply into the Shoshone National Forest, where prominent landmarks like Sheep Point and Pappapau Butte overlook the waterways. The map documents modern accessibility through routes such as Pitchfork Rd and the Dick Creek Access, showing how the cattle ranching heritage of Park County continues to coexist with vital water conservation efforts and public wilderness lands.
