Jamba, one of the great dogs of Waterville Valley, and the most beautiful red labradoodle in the world, passed away in 2017 after 11 plus years with me.
On our daily trips to Town Square, Jamba was in this part of the Mad River whenever it was not rushing or frozen.
Go to the bridge over the Mad River on West Branch Road, just below the pedestrian walkway. Look south -- Jamba's pool is between the concrete ledge in the river and the big rock. To find the cache, you do not have to get wet! See the dirt path going by the pool on the left bank? Go over there. The cache is nearby.
