September 1997

Trail Description:

This most interesting trail circles Mount St. Helens, allowing you to experience the effects the 1980 eruption had on the mountain and the surrounding area. It is a challenging hike across rock fields, canyons of every size, many dry washes and gullies, and chunky lava flows. Most of this trail is at or above timberline. There is no water at the trail heads and water availability on the trail is limited.
