The monster of Lake Memphremagog on the American-Canadian border is well-known to monsterologists. The head has been said to resemble that of a dragon. Widely varying elements of length have been given, perhaps indicating the existence once again of more than one monster. It has been reported since the 19th Century. The creature is thought to live in a deep part of the lake under Owl's Mountain.
Reports of the Lake Manitou Monster continued until at least 2006. The Potawatomi Indians believed there was a monster in this Indiana lake and a number of alleged sightings were reported in the Logansport Telegraph in 1835. There have been discoveries of mastodon bones in the area and Roy Mackal has suggested that they may have given rise to the Indian legends. Of course, maybe the monster ate mastodons and spit out the bones. The monster is said to be 60' long. Its head was described by one witness as resembling a cow's.
