According to Seneca mythology, the Gaasyendietha is a meteor dragon that dwells in the deep areas of rivers and lakes of Canada, especially Lake Ontario. Not only did the Gaasyendietha spew fire, it could also cross the heavens on a trail of fire. The name Gaasyendietha was offered by native people to French explorer Jacques Cartier when he inquired about a creature briefly sighted by him and his crew in the St. Lawrence River.
They described the creature as a blue giant finned snake that moved like a caterpillar. Some argue that Gaasyendietha is the product of meteors, while others claim that this is a meteor fire dragon.
