is a high mountain pass in the San Juan Mountains in the southwest part of the US state of Colorado. It crosses a ridge connecting Ouray, Colorado with Telluride, Colorado, and is the highest mountain pass in the San Juan Mountains, and the second highest vehicular mountain crossing in Colorado. From Ouray, the road turns off the road to Yankee Boy Basin above the Camp Bird Mine near the ghost tow
n of Sneffels southwest of Ouray, and climbs through Imogene Basin to the summit. From Telluride, the road takes off north of downtown and climbs past the ghost town of Tomboy through Savage Basin to the summit. "Fort Peabody" was constructed in 1904 by a local unit of the Colorado National Guard on top of the pass to prevent union miners from crossing during a labor strike. An annual foot race is held over the pass between Ouray and Telluride on the first Saturday following Labor Day. This gruelling race starts at around 7800 ft (2377 m), is 17 miles (27.3 km) in length, and crests on the pass at 13,114 ft (3997 m), a change in elevation of just over a mile.
