2020 Map of Bison Mountain
USGS Topo · Published 2020About this map
Irish Mine Hill and the surrounding high ridges of the Helena National Forest define this landscape where Jefferson and Powell counties meet. The terrain is characterized by steep drainages and isolated landmarks such as Treasure Mtn and Bison Mt, connected by a network of forest roads and the high-altitude Continental Divide National Scenic Trail. Waterways like the Little Blackfoot River and Monarch Creek cut through deep ravines, while Blackfoot Meadows offers rare open ground in the southern reaches.
