Chosen answer: The actual name is Bluejohn Canyon. According to online tourist info for Utah, "It appears to have been named after a minor Robbers Roost outlaw by the name of John Griffith. Griffith had one blue eye and one brown eye and thus was saddled with the nickname "Blue John." It is recognized that he kept stolen horses in the area, perhaps watering them at nearby springs. In the fall of 1899 Griffith is reported to have put in at Hite with a small boat with the intention of reaching Lee's Ferry. He was never heard from again."
