The Lewis and Clark Range dominates this 2017 survey, where three major wilderness jurisdictions converge at a significant hydrological junction. High-altitude peaks including Trident Peaks, Flint Mountain, and Evans Peak define the divide between the Flathead National Forest, Lolo National Forest, and Lewis & Clark National Forest. This confluence of administrative boundaries centers around Triple Divide, a point marking the separation of western and eastern drainages. To the north, the S Fork Sun River and Sun Lake gather waters heading toward the Missouri River system, while the south-facing slopes feed the Dry Fork N Fork Blackfoot River and Dwight Cr, leading toward the Columbia River basin. The map detail highlights the sparse, non-residential nature of this high-country terrain, focusing on the intricate network of alpine creeks like Bar Cr and Cabin Cr that carve through the limestone-rich slopes of the northern Rockies.
