1995 Map of Thunder Mountain

About this map

The Little Belt Mountains define this high-altitude section of the Lewis and Clark National Forest, where the landscape is carved by an intricate network of drainages. The Kings Hill Ranger District manages this area, which is anchored by the prominent peaks of Thunder Mountain and Big Horn Mountain. The map reveals a history of resource exploration, indicated by several prospects scattered near the headwaters of Spring Creek and across the ridgelines. Movement through the steep terrain is facilitated by primitive routes like the Circle Trail, while the deep cuts of Tobins Gulch, Goblin Gulch, and Holter Gulch illustrate the erosive power of the local watershed. This 1995 revision provides a clear record of the boundary between Cascade and Meagher counties as it crosses these summits, showing the land just as it remained before modern digital mapping updates.
