The town started in the 1880s as a saloon and water-refilling station for the Denver and Rio Grande Western Railroad. As work crews and, later, travelers came through, stores, hotels and restaurants sprang up to accommodate them. Nearby cattle ranchers and sheep herders in the Book Cliffs north of town began using Cisco as a livestock and provisioning center. Around the turn of the 20th century sheep were sheared at Cisco before being shipped to market. After oil and natural gas were discovered, Cisco continued to grow. The town's decline coincided with the demise of the steam locomotive. Cisco's already declining economy crashed when Interstate 70 was built, bypassing Cisco.
