The Letterbox is at the listed coordinates but you won't need a GPS to find it. Here are the Letterbox clues:
From the WMA parking area go under the power lines, stay to the left and go over the wooden bridge. A short distance up the first hill you will see a sign that is significant to this letterbox. From this sign look up the hill to your left and you will see a tree shaped like the letter Y. Eight paces past this tree you will find a three trunk tree. The letterbox is in this tree.
Please do not remove the stamp or ink pad from the Letterbox.
This, and two more near by letterboxes can be found at Letterboxing North America. Boundary Forrest Frog Fall Folliage at the Cobbles
