The Dominguez-Escalante expedition was the first on it, traveling from Utah Lake to present-day Scipio. Jedediah Smith traveled most of it in 1826 and 1827, and other trappers, including Ewing Young, Kit Carson, and Peter Skene Ogden, followed. John C. Fr?nt mapped the country up to Utah Lake in 1844, and in 1848 Miles Goodyear took a pack train over the entire Salt Lake-Los Angeles route.
The ancient Pueblo People, also known as the Anasazi, built large communities in southern Utah from roughly the year 1 to 1300 AD. The Ute Tribe, from which the state takes its name, and the Navajo Indians arrived later in this region. Salt Lake City was founded on July 24, 1847, by a group of Mormon pioneers. (Mormons are members of the Church of Jesus Christ of Latter-day Saints.) The pioneers, led by Brigham Young, were the first non-Indians to settle permanently in the Salt Lake Valley.
