Mount Rainier is much more than a mountain in the sky. Constructed of hundreds of lava flows, and capped by as much glacier ice as all other Cascade volcanoes combined, Rainier’s steep rubble slopes and abundant water make it prone to landslides and lahars (volcanic mud-flows), especially during eruptions. Lahars are the biggest hazards to the area. Scientists and emergency officials watch and warn.
Evacuate
Evacuate by vehicle or on foot to high ground above the valley floor. Do not stop to look, continue as directed.
Find Shelter
Guidelines If you are safe from lahars and ash is falling, seek shelter in a building or vehicle.
