About this map

Helena National Forest dominates this high-altitude landscape along the border of Broadwater and Gallatin counties. The terrain is defined by the significant rise of Sixmile Mountain and Blacktail Mountain, creating a network of steep drainages including Sawmill Gulch, Haw Gulch, and the prominent Rocky Canyon. The presence of Prospects near the eastern boundary suggests the historical interest in mineral extraction that often drew early settlers into these more remote reaches of the Big Belt Mountains.

Water management and natural flow are central to the landscape, with Dry Creek and Sixmile Creek carving paths through the timbered slopes. Names like Miners Gulch and Meyers Gulch reflect the legacy of those who worked the land. The map also traces the winding course of Poddys Run and Timber Gulch, providing a detailed look at the hydrology and land-use patterns of this mountainous region in the mid-1980s.
