Hummocks Loop

Hummocks Loop Professional Review and Guide

"This is a relatively short and easy hike through the remains of the 1980 Debris Avalanche. You should have plenty of time to stop at the points of interest before reaching the trailhead or (better) on the way back. The entire Hummocks Loop wanders through the jumbled, mounded, and chaotic (hummocky) landscape of the remains of the Debris Avalanche deposited by the May 18, 1980, eruption of Mount St. Helens.

The huge landslide swept the upper 1,300 feet of the peak into the valley of the North Fork Toutle River. Some of the rocks and other volcanic debris you see along the route may have been at 9,000-feet-plus elevation near the summit of this once much higher, symmetrical mountain. Roosevelt elk (Cervus elaphus roosevelti) are very common along this trail in spring; I saw more than a hundred of them when I hiked this trail in April. Coyotes (Canis latrans) can often be seen or at least heard, especially if you’re on an early-morning hike."
