See #01 Jessica’s Jaunt for full details of the series.
This is a small click-lock container. It is NOT in the tree roots at the FRONT of the tree - I am being specific on this point as it is clear that some cachers have, unfortunately, been somewhat over enthusiastic in rooting around in the roots and over time quite a "cave" has developed between some of the front roots.
Please note that this cache is not in the overly obvious place at the front of the tree.
