Vernal, Uintah County's largest city, is located in eastern Utah near the Colorado State Line, and 175 miles east of Salt Lake City. It is bordered on the north by the Uinta Mountains, one of the few mountains ranges in the world which lie in an east-west rather than the usual north to south direction. The Book Cliffs lie to the south, and Blue Mountain to the east, while Vernal itself lies in Ashley Valley, named in honor of William H. Ashley, an early fur trader who entered this area in 1825 by floating down the Green River in a bull boat made of animal hides. Vernal, unlike the majority of Utah towns, was not settled initially by Mormon pioneers. Brigham Young sent a scouting party to Uinta Basin in 1861 and received word back the area was good for nothing but nomad purposes, hunting grounds for Indians and "to hold the world together." That same year, President Abraham Lincoln set the area aside as the Uintah Indian Reservation. Captain Pardon Dodds was appointed Indian agent for this reservation.

Utah (/ˈjuːtɔː/ or ⁱ/ˈjuːtɑː/) (Arapaho: Wo'tééneihí' ) is a state in the Western United States. It became the 45th state admitted to the Union on January 4, 1896. Utah is the 13th-most extensive, the 34th-most populous, and the 10th-least-densely populated of the 50 United States. Approximately 80% of Utah's 2,817,222 people live along the Wasatch Front, centering on Salt Lake City. This leaves vast expanses of the state nearly uninhabited, making the population the sixth most urbanized in the U.S. The name "Utah" is derived from the name of the Ute tribe and means "people of the mountains" in the Ute language. Utah is bordered by Arizona on the south, Colorado on the east, Wyoming on the northeast, Idaho on the north and Nevada on the west. It also touches a corner of New Mexico.

Utah is the most religiously homogeneous state in the Union. It is home to the Salt Lake Temple, and approximately 60% of Utahns are reported to be members of LDS Church which greatly influences Utah culture and daily life.
