Timberline Trail, Circular mountain trail at Mount Hood, Oregon, United States

The Timberline Trail is Forest Service trail #600, a loop of roughly 41 miles around Mount Hood in Oregon that alternates above and below the timberline. It shares eleven miles with the Pacific Crest Trail and crosses steep canyons, where loose rock and dirt drop away and meltwater runs down the path past patches of snow.

The Timberline Trail was built in the 1930s by the Civilian Conservation Corps, most of the work done in summer 1934 at a cost of $10,000. Landslides and washouts have forced reroutes since. In September 1938 a group of hikers circled the whole 36-mile trail in 47 hours, which made local news and drew attention to the route.
