In the 1960s a teenager from Sherman (NY)told John Keel that creatures from a nearby swamp had been reported by a number of witnesses. They sometimes walked on four feet, sometimes on two. (the creatures, that is, not the witnesses). They were covered in white hair and, when standing upright, they were 12'-18' tall. They also had long tails, 6'-8'.
This cryptid would seem to be an isolate, but we would welcome reports of anything similar.
