Osceola Mudflow

— Mather Memorial Parkway —

Mud on the Move. Along with lava and ash, the
volcanically active Mount Rainier has contributed thick flows of mud from its sides and summit. One of the largest mudflows occurred about 5,800 years ago sending thick rivers of mud down the White River drainage.

These flows carried rock and huge boulders, some 35 feet tall and several hundred feet around, from the mountain's slopes to the surrounding lowlands.

Osceola Mudflow. The largest of the mountain's historic flows, the Osceola mudflow covered an area of about 100 square miles. It buried the present town site of Enumclaw (24 miles west of here) under as much as 70 feet of debris.

Seismic activity triggered the mudflow, resulting in the collapse of nearly 2,000 feet of Mt. Rainier's summit.
