Campground obliterated as slide triggers 'tsunami'

Campground obliterated as slide triggers 'tsunami': "Penner said the incident likely occurred during Monday's rain storm when part of a nearby mountain slid into the western end of the lake. Since then, about two hectares of debris has been pushed to the eastern end of the lake, where it meets the Chehalis River, a tributary of the Harrison River, he said. The water appeared to have rocked back and forth on either side of the lake, pulling trees and brush into the lake, he said. 'A big chunk of a side of a mountain let go,' Penner said, describing the devastation he witnessed. 'The wall of water that was pushed up out of the lake was at least 30 to 40 feet high as it came ashore at the west end of the lake.'"
