The Uintah and Ouray reservation is located in Northeastern Utah (Fort Duchesne) and is approximately 150 miles east of Salt Lake City on US Highway 40. The reservation is located within a three-county area known as the "Uintah Basin". It is the second largest Indian Reservation in the United States that covers over 4.5 million acres. Over half of its membership lives on the Reservation. Families enjoy fishing and hunting. The U&O provides for us in so many ways.
