Artist rendering of the Osceola Mudflow releasing from Mount Rainier.

About 5,600 years ago the summit and northeast face of Mount Rainier fell away in a massive landslide accompanied by volcanic explosions. The Osceola Mudflow, a towering wall of mud and rock, thundered down the White River Valley where it deposited 600' of debris eventually reaching the Puget Sound.
