2020 Map of Thunder Mountain

About this map

The Little Belt Mountains dominate this high-altitude section of the Lewis & Clark National Forest, where steep drainages and sharp peaks define the topography. The terrain is characterized by a series of prominent summits including Thunder Mountain, Big Horn Mountain, and Mt Pilgrim at the southern boundary. This area serves as a significant watershed, with numerous named gulches and creeks feeding into larger systems. Waterways like Pilgrim Creek, Belt Creek, and Deer Creek wind through deep cuts in the landscape, reflecting a geological pattern of heavy erosion and established drainage paths. The naming conventions of features like Sawmill Gulch, Goblin Gulch, and Circle Gulch suggest a history of early exploration and resource identification in this part of Cascade and Meagher counties. Human imprint is limited to a few access points such as Logging Creek Road and Jamestown Lane, leaving much of the area in its natural state.
