Historical Timeline

Originally a river crossing for the Old Spanish Trail and later used by the Ute Tribe. The town was established in the late 1870s as a mail station between Salina, Utah, and Ouray, Colorado. Its growth was fueled by the Denver and Rio Grande Western Railroad and its selection as a base for John Wesley Powell’s 1869 and 1871 expeditions. During the mid-20th century, it became a strategic site for the Green River Launch Complex, used to test Athena and Pershing missiles.
