2020 Map of Hooky Dam

About this map

Sheep Cr and its various tributaries carve through the high plains of Eastern Montana in this modern topographic study. The landscape is defined by its drainages, including Lumpjaw Cr, Lone Tree Cr, and Trail Cr, which create a complex network of coulees and ridges. A significant man-made landmark, Hooky Dam, is situated along Back Cr near the border of Fallon and Custer Counties. The region remains primarily open range, with transportation limited to remote corridors like Foundation Rd and Rd 428. This map captures the intersection of three counties—Fallon, Custer, and Carter—providing a precise record of these rural boundaries and the natural watercourses that have historically dictated land use and ranching boundaries in this corner of the state.
