2020 Map of Sixmile Mountain

About this map

Helena National Forest lands dominate this high-altitude landscape along the border of Broadwater and Gallatin counties. The topography is defined by a series of steep drainages, most notably the namesake Sixmile Mountain and the deep cleft of Rocky Canyon. The drainage patterns here reveal a legacy of early resource extraction and timbering, evidenced by names like Miners Gulch, Meyers Gulch, and Sawmill Gulch. Waterways such as Sixmile Creek and Paddys Run cut through the terrain, while routes like 6 Mile Rd and Dry Creek Rd provide the primary access into these mountain heights. This survey captures the region's character as a managed wilderness, where the historical nomenclature of the gulches hints at the prospectors and laborers who once worked these slopes.
