Beaverhead National Forest land dominates this high-altitude terrain, where the boundary between Madison and Beaverhead counties follows the natural drainage divides. The landscape is defined by massive ridges and peaks, from Monument Hill in the northwest to the eponymous Windy Hill and Divide Mtn further south. Waterways carve deep basins into the range, including the Elk River and the headwaters of the W Fork Madison River which flows across the southern flats. The Gravelly Range Rd provides the primary transit route through this complex topography, passing near landmarks like Crater Ridge and Wolverine Basin. For those interested in mountain geography, the map reveals a network of named peaks and canyons, including Cascade Mtn and Dry Gulch, showing how early surveyors identified this remote section of the Montana Rockies.
