S1 E6 The Osceola Mudflow, also known as the Osceola Lahar, was a lahar in the U.S. state of Washington that descended from the summit and northeast slope of Mount Rainier during a period of eruptions about 5,600 years ago. It traveled down the west and main forks of the White River, passed the location of present-day Enumclaw then reached Puget Sound near present-day Auburn. The Osceola collapse formed a 1.8 km (1.1 mi) wide horseshoe-shaped crater, open to the northeast, almost the same size as the crater produced by the 1980 eruption of Mount St. Helens. Most of the Osceola crater has been filled in by subsequent lava eruptions, most recently about 2,200 years ago.
