Champ

Champ is a cryptid thought to live in Lake Champlain in New York, Vermont, and Quebec. It is often recognized by  a famous photo  called “the Mansi photograph.” It has a thick body with a tapered neck, resembling a plesiosaur, though some describe it as a massive serpent. Some believe it may be related to a horned lake monster from Iroquois Native Americans. Reports appeared in newspapers around 1873 and P.T. Barnum offered a $50,000 reward to any who could bring the monster in, and of course, no one claimed this reward. It isn’t thought to be aggressive and features prominently in local tourism.
