I came over to this park for a run today and decided to hide some caches while I was here. On my route, I spotted this tree and decided to hide a cache up it.
You are looking for a black bison tube. It is visible from the ground, but not easily. At least not in June.
Climb at your own risk.
You must get your name on the log in order to claim this cache as found. The terrain is rated as a 4.5 for a reason. Simply seeing the cache from the ground does not count. I have had to delete too many logs on this cache by now. If you don't feel safe, get a ladder or a friend to climb for you.
