Under the direction of John Taylor, Silas S. Smith and Danish settler Jens Nielson led about 230 Mormons on expedition to start a farming community in southeastern Utah. After forging about 200 miles of their own trail over difficult terrain, the settlers arrived on the site of Bluff in April 1880. The town was named for the bluffs near the town site. The town's population had declined to seventy by 1930 but rebounded during a uraniumprospecting boom in the 1950s. With the uranium decline in the 1970s Bluff again declined and now remains a small town with about 200 residents.
