Most of Mt. St. Helens’ summit slumped to the north and slid down the Toutle River valley during the mountain’s 1980 eruption. The slide dammed 4-mile-long Coldwater Lake and left an eerie collection of 200-foot-tall hummocks strewn across the valley floor. You can view the results of this volcanic mayhem by hiking along the new lake’s shore to a dramatic bridge over a gorge. Nearby, an easy loop trail tours the weirdly scenic Hummocks.
