About this place

Hike among the "hummocks", huge pieces of Mount St. Helens that slid off and were part of the massive 1980 landslide. The north flank collapsed and slid away, slamming into a ridge that diverted it west into the Toutle River Valley for 14 miles. This new landscape, initially barren, now teems with life. View the returning forest, wetlands and ponds on this relatively easy, 2.5-mile loop trail. Connect with Boundary Trail #1 to head east toward Johnston Ridge Observatory. From Castle Rock, WA head east on State Highway 504 (Spirit Lake Highway) for 42.7 miles take the right branch and stay on 504 and drive another 2 miles to the Hummock/Boundary Trailhead on the right.
