Walk the Pacific Northwest coast and you’ll see “ghost forests” where dead trees stand bleached white against gray winter skies. These eerie markers show where the land dropped suddenly in 1700 during the last mega-wave event. The Native American stories tell of giant waves that swallowed entire villages. Japanese records confirm the 1700 wave crossed the Pacific. Scientists have found evidence that these massive waves strike every 300 to 600 years. We’re overdue.
