Bluff (Navajo: Tséłgaii Deezʼáhí) is a town in San Juan County, Utah, United States.

[5] Under the direction of John Taylor, Silas S. Smith and Danish settler Jens Nielson led about 230 Mormons on an expedition to start a farming community in southeastern Utah.

After forging about 200 miles (320 kilometers) of their own trail over difficult terrain, the settlers arrived on the site of Bluff in April 1880.

[6] (The trail followed went over and down the "Hole in the Rock", which now opens into one of the tributaries of Lake Powell.)

[7] The town's population had declined to seventy by 1930[citation needed] but rebounded during a uranium prospecting boom in the 1950s.

[citation needed] Bluff is located in the sparsely populated southeastern Utah canyonlands of the Colorado Plateau.

Bluff is located in hardiness zone 7A, with an average yearly low of 1 °F (−17 °C).

Temperatures are usually warm, although snow has fallen as late as April (although very rarely).

35.6% of all households were made up of individuals, and 5.2% had someone living alone who was 65 years of age or older.
