The Pioneer Mountains dominate this high-altitude landscape within the Beaverhead National Forest. This modern study shows the complex watershed of the Big Hole Divide, where numerous drainage systems such as Wyman Creek and Old Tim Creek carve through the terrain. The presence of the Pyle Ditch in the southeastern corner near Grasshopper Valley reflects the region's managed water systems, while Maverick Mtn stands as a central topographic anchor. Transport is limited to primitive routes like Kinselman Creek Rd, emphasizing the wilder character of this portion of the forest. The map provides clear detail of the headwaters for several tributaries including Blue Creek and East Fork Pole Creek, which feed the larger drainage basins at the base of the mountain ranges.
