Cisco is a ghost town in Grand County, Utah near the junction of State Route 128 and Interstate 70. At one time the town served as a saloon and water-refilling station for the Denver and Rio Grande Western Railroad. The town's decline coincided with the demise of the steam locomotive. The town site contains many relics of a typical old west railroad town. Cisco survived long enough into the 20th century to be assigned a ZIP Code, 84515.
