Brigham Young apparently crossed the Mississippi by ferry in 1847 to begin the trek to the Salt Lake Valley, according to the official record of The Church of Jesus Christ of Latter-day Saints, rather than crossing the river after it was frozen, as reported March 31 in the story of the history of the Nauvoo Brass Band.

However, family records of the period and The History of Salt Lake City say that he and the band crossed on the ice, showing conflict between official and individual family history.
