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. The road is accessible by four wheel drive vehicles, and is not for the novice driver.
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.
