The confluence of the forks of the Powder River defines this landscape in central Wyoming, where the N Fork Powder River, Middle Fork Powder River, and S Fork Powder River converge. This 2015 survey reveals a complex network of ranching and irrigation infrastructure, including the Sussex Irrigation Canal and several man-made waterways like Miles Ditch and Modoc Ditch. The presence of Coal Mine Rd and Ttt Rd hints at the region's industrial and agricultural history, while Old Highway 87 traces a former primary transport route through the southwestern corner.
