Lewis and Clark National Forest encompasses the high-elevation terrain of the Big Snowy Mountains in this mid-1990s revision. The landscape is defined by dramatic ridgelines, including the prominent Black Ridge and the sharp profile of Knife Blade Ridge. These geologic features serve as the headwaters for several drainage systems, with Big Rock Creek and its forks—the East Fork, West Fork, and Timber Creek—carving deep canyons through the limestone.
