Paul Bunyan is a giant lumberjack in 19th-century folktales. The tales describe how Paul ate enormous quantities of food. He could chop down the largest trees with two strokes of his axe. Helped by the mighty blue ox, Babe, he hollowed out the Great Lakes, created the Bay of Fundy tides, and raised up the Rocky Mountains. In one of his adventures, Paul decided to straighten out a crooked river. He tied Babe to a tree on the bend of the river and, with one strong pull, he drew out 15 km of bends.
