You are looking for a bison tube container close to the largest trunked tree at the end of a small row of trees along the 'concrete path' from the end of the Braughing Bone to Bozen Green. You will need to look closely, perhaps from the lower level, just by the path.
This cache is located in the beautiful countryside, just outside Braughing. The cache is located near the Braughing Bone, a fantastic place to explore in all seasons. This cache is only accessible by foot.
