On one of our first visits to Blue Mountain we ended up on one of the winding, serpentine trails in the middle of the park and wandered back and forth enjoying the scenery. You'll find this cache just off one such trail near what I have dubbed swiss cheese butte - due to some interesting holes in the rock.
You are looking for a standard size ammo can placed into one of these holes.
Several parking options are available. There is a reasonable sized parking lot on the west side at Montrose Station Road and Washington Street. Alternatively, you can find street parking in the cul-de-sac on the east side where Montrose Station Road continues on the other side of the park.
There is a clue taped in the lid, and also found in the log book that will lead to the Go Fish (visit link) mystery cache.
