Our next stop was Thunder Hole. A recess in the rocky shoreline combined with an undercut area in the rocks makes for a narrow channel that waves slam into and compress air in a pocket under the rocks. As the waves recede, the compressed air explodes out making a thunderous boom. Or so the sign says.
Our first experience at Thunder Hole made us think it should be called Gurgle Hole.
