So Now You Know

Mistpouffers are unexplained reports that sound like a cannon or a sonic boom. They have been heard in many waterfront communities around the world such as the banks of the river Ganges in India, the East Coast and inland Finger Lakes of the United States, as well as areas of the North Sea, Japan and Italy; and sometimes away from water. Around Seneca Lake and Cayuga Lake in the USA, they are known as "Guns of the Seneca" and, well, by other names as well (check out the link for more info on names).
