Early on March 22, 2014, the most damaging landslide in U.S. history devastated the community of Oso, Washington. Forty-three people perished, most inside their homes, when a saturated hillside nearby gave way and a massive mudflow swept over their neighborhood. On July 22, a search crew recovered the last of the 43 bodies, exactly four months after the landslide, and coincidentally on the same day, a team of scientists and engineers released an exhaustive report detailing the event and its implications.
