Congrats! You're almost to the end of the main trail. Once you find the cache you can continue a few hundred feet down the trail to the end, where you can stop and dip your feet in the water. Also a great place for a drink if you have a lifestraw. This cache is a Bison cache a few feet off the trail. Please leave it exactly how you found it.
Congrats to denbomans for FTF.
