Big Hole Divide forms the primary topographical spine of this region, separating the drainage systems within the Beaverhead National Forest. This 2014 survey documents a landscape defined by an intricate network of creeks, including the Left Fork Swamp Cr and Right Fork Swamp Cr in the north, and the extensive Buffalo Creek system to the south. The presence of Buffalo Creek Rd and Reservoir Creek Rd indicates the primary corridors of movement through these high-altitude basins. To the east, the terrain opens into the Grasshopper Valley, a distinct contrast to the more confined geography of Brays Canyon and Browns Canyon. The map provides a detailed view of these natural drainages before they exit the forest boundary, illustrating the complex hydrology of the Middle Fork Buffalo Cr and its various tributaries like Straight Fork Buffalo Cr.
