Quote:The falls got their name from the Laughing Whitefish River. At the mouth of the river, where it empties into Lake Superior, the Ojibwe from Lake Superior said to looked like a laughing whitefish. The scientific explanation credits an abrupt limestone ridge, and the bank cascades out into a fan-shaped wall of water, which to some looks like the mouth of a fish.
