Whale Rock is a large glacial erratic located at the Thayer Brook conservation area. This cache will take you to the area of the rock and then off the beaten path to GZ. This area is popular with kids and adults alike for hiking & rock climbing so I placed the container out of the way to hopefully avoice muggling so it will require a bit of a bushwhack for the last 50-75'.
