Just before midnight, the foundation—built on unstable geological formations—collapsed catastrophically. The concrete structure itself remained largely intact as it slid away. Over 400 people died in the Santa Clara River Valley as the floodwaters rushed 54 miles to the ocean. Dam designer William Mulholland's career en
