The Middle Fork Powder River carves a central path through this high-altitude landscape on the boundary of Johnson and Washakie Counties. This 2021 survey reveals a complex drainage network where deep canyons and named slopes like North River Slope and Dry Vee Slope define the topography. The map illustrates a watershed dominated by seasonal and perennial flows including Gordon Cr, Sullivan Cr, and the converging waters of Poker Cr and Little Eagle Cr. This is a territory of specialized ranching and public land management, where the physical geography dictates the placement of backcountry access roads and property lines. The detailed hydrography of small tributaries such as Bachaus Cr and Carpenter Cr provides essential spatial data for researchers tracking historical land use and environmental changes in the Powder River Basin region.
