Paul Bunyan

From Conservapedia

Paul Bunyan is a figure from American folklore. Paul Bunyan was described as a giant woodsman, who - along with his equally prodigious ox, Babe, was used to explain many of the features of the natural world that settlers encountered in the western United States. Legend says that the Grand Canyon was gouged from the surface of the earth when Paul dragged his axe behind him.

He's rumored to have had a similarly-sized blue ox, named Babe.
