Old Sticks in the Mud: Hazards of Lahars from Mount Rainier Volcano part of Curriculum for the Bioregion:Activities
Volcanic debris flows (lahars) flow long distances, bury and aggrade river valleys, and cause long-term stream disturbances and dramatic landscape changes. Students will evaluate the nature, scale, and history of past lahars from Mount Rainier in a river valley and interpret the past and potential future impact on humans of lahars.
