Imogene Pass, Mountain pass in San Juan Mountains, Colorado

Imogene Pass is a 13,114 ft (3,997 m) mountain pass on a ridge in the San Juan Mountains, connecting Ouray and Telluride. From Ouray the road climbs through Imogene Basin past the ghost town of Sneffels; from Telluride it rises past the ghost town of Tomboy through Savage Basin. It is the highest pass in the San Juan Mountains and Colorado's second-highest vehicular crossing.

In 1904, the Colorado National Guard built Fort Peabody at the summit of the pass. The fort was constructed to help monitor mining activity during a major labor conflict in the region.

The Imogene Pass Run happens each year after Labor Day, drawing hundreds of runners to tackle the demanding mountain route between Ouray and Telluride. The race has become a key event in the mountain community's calendar.

Crossing this pass requires a four-wheel drive vehicle and an experienced driver to safely navigate the steep, rocky terrain. The best time to attempt the crossing is between June and early October, when snow has melted.

This area hosted one of the first long-distance alternating current power lines, which carried electricity from Telluride to the Camp Bird Mine. This engineering achievement was groundbreaking for power distribution in its era.
