The Lewis & Clark National Forest dominates this high-altitude landscape, where the Continental Divide National Scenic Trail winds through the southwestern corner. The terrain is defined by prominent peaks and ridges, including the landmark Steamboat Mountain and Lone Chief Mountain. Water courses such as the Dearborn River and its tributary Milky Stream carve through the deep drainages, with the river passing through the notable Devils Glen and Skull Gulch.
