On the western edge of Mt. St. Helens’ 1980 blast zone, this hike has a little of everything: intact old-growth forests, desolated canyons, wildflower-strewn timberline meadows, and a truly astonishing view of the mountain from the South Fork Toutle River’s gorge, where the river has cut a sandy chasm into a half-mile-wide mudflow unleashed by the flash melting of the Toutle and Tallus Glaciers. Since then, smaller mudflows have periodically blocked car access to this hike’s trailhead. For current conditions, check or call 360-449-7800.
