Widtsoe is a ghost town in Garfield County, Utah, United States. It is located in John's Valley, northeast of Bryce Canyon and along the Sevier River at the mouth of Sweetwater Creek. A small number of settlers arrived in the area in 1876 and it became a town around 1908 after farmer Jedediah Adair was followed by a more significant population. Initially known as Adairville, after Adair, the town later became Houston and Winder, before attaining its final name after John A. Widtsoe, the president of and an agricultural scientist at the University of Utah. The population declined significantly from 1920 following droughts, and the town emptied in 1936. Most buildings were demolished shortly afterwards.
