1986 Map of Sixmile Mountain

USGS Topo · Published 1986

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.
