On April 5, 1972, the deadliest tornado in Pacific Northwest history hit Portland and Vancouver.

The F-3 twister started in Portland, jumped the Columbia River and cut a 9-mile path of destruction from East Vancouver to Brush Prairie.

Six people died and more than 300 were hurt, including 70 children at Peter S. Ogden Elementary.
