Salt Lake is a city built on secrets. Its origin tale is wrapped up with the “Bible 2.0” Exodus of Brigham Young and his followers, the Latter-day Saints, members of The Church of Jesus Christ of Latter-day Saints (officially) or the Mormons (colloquially and historically). The Mormons first arrived here in the Great Salt Lake Valley on July 24, 1847, from Nauvoo, Ill. Brigham wanted his followers to be left alone to practice the LDS faith and, yep it gets weird, to establish a short-lived autonomous nation called the Kingdom of Deseret. It is, as we say around here, a heck of a story.
