The proposed Great Burn Wilderness never disappoints, of which this 50+-mile loop is proof. Kelly Creek is a world-renowned blue ribbon trout stream and the backcountry is rich with large game animals, including moose, elk, blackbears, and wolves.
The Mastodon Mountain loop makes for a great early summer hike, when higher elevations are still snow-covered. The highlights are the beautiful walk through Slate Meadows and along Slate Creek as well as the grandiose views from Mastodon Mountain. The lowlight is the utter lack of water on the ridges: make sure you carry plenty!
