Finding this cache should be easy. Getting the log out is not. You are seeking a bison tube with metal bits attached to the bottom and top. It is hidden in the box. The box is sealed and there is no way in except by using a mysterious force.
Your job is to learn how to wield the wizards power and extract the bison tube from the box. You do not need to use strength; just some manual dexterity, wizardry magic, and a tad bit of luck. All of the required tools are provided for you. All you need is to think like a wizard (or at least like a physicist).

The cache is located just off the Happy Valley Greenway behind a large grove of trees. It is about 0.35 miles from parking. The trail is smooth and flat, so should be accessible to one and all. This is a good one for the kids, tho the younger ones may have issues solving the puzzle (but then, thats what supervising adults are for - so my best recommendation for this cache is to bring adult supervision). Only one person is required to solve the puzzle.
