Also known as N'Haatik, or the Demon of the Lake, the legend of Ogopogo first appeared in Native American folklore.
Ogopogo makes his (or her) home in Okanagan Lake in British Columbia, Canada. As with most cryptids, its home territory makes it extremely difficult to find. The lake itself is large and deep, nearly 84 miles long and 860 feet at its deepest point.
The Canada's British Columbia tourism website, whose motto just happens to be "Super, Natural" claims there are, on average, six Ogopogo sightings each year.
If you're one of the lucky few to glimpse the famous monster, it's said to resemble a cross between a giant snake with the head of a goat or horse. Or, if you're a dinosaur buff, some say Ogopogo resembles a plesiosaur.
Despite its "monstrous" reputation, Ogopogo has quite the following of beloved fans. The city of Kelowna has commemorated the creature in everything from art to parade floats.
