The idea behind monsters has been around for centuries and throughout all that time, there are always those who firmly believe in their existence. None of us want to think there are creatures that go bump in the night or otherworldly apparitions that are just waiting to reach out and grab us when we're vulnerable, but there's also a certain allure to the fear.

Mythical beings and swamp-side creatures that are rooted in folklore had to come from somewhere, and many of these stories have been passed down from tribes and native peoples who swear to know of their existence. So who are we to judge what they claim to have witnessed? North America is a hub rich in folklore and a place not many would expect to stumble upon such devious monsters.

We're here to tell you that you'd be surprised to know how many are supposedly lurking just below - or above - our feet.
