You will find this cache amomg many others in the Ninham Mountain Multiple Use Area off of Gypsy Trail Road in Putnam County N.Y.
Park at the top of Mt. Ninham Ct. (way point below) and take the trail that goes to the left from the kiosk (Coles Mill Road) and follow it for a third of a mile or so to this location. You are looking for a small tube about the size of a pre form here and this is a log only cache for all intents and purposes. There is a pencil in the container but it is always a good idea to bring your favorite writing utensil with you when you come just in case..................The cache is NOT in or on the rock wall although you have to cross over the wall to get to the area of GZ. But don't fret there is an opening very close by.....................Growing in the area of the cache looked like blue berries to me hence the name of the cache. .................Please put the container back as you found it, and watch your step going over the wall.................. and remember that there is hunting in this area so be sure to wear something orange during hunting season if you come then.................There are lots of other geocaches in this area that you can find here and a lot of trails, not to mention the fire tower that is up the right hand trail from the kiosk..............So have a nice hike and as always Have Fun, Be Safe, and Enjoy!
