Cache is NOT at the posted coordinates – they are your starting point to finding GZ. DO NOT try to access GZ from the Don Valley Parkway.
Cache is an ammo can containing a log book, self-inking stamp and stamp pad, plus trade items, with room for trackables. Please do not remove the stamp or the stamp pad from the cache -- they are not trade items.
From the starting point, go down the slope until you are standing on the trail. Turn right and go along the path a ways, until you see three grey posts, each a different height, roughly aligned in a row between the trail and the fence above. With the posts behind you, head down the slope about 36 meters. See the big three-trunked tree? Look to the left of that to start your search.
Please be sure to replace the cache and its camouflage exactly as you found it.
