Welcome to Moose Meadow. All of the small brooks and creeks in the area, including the one by this cache, empty into Moose Meadow Brook which empties into the Westfield River, then the Connecticut River, and finally the Atlantic Ocean.
Maybe if you place a message in a bottle into this brook you will find it the next time you go to the beach??? A long shot I'm sure. Cache is a bison tube in the woods. ;-)
