Mount Rainier Active Volcano


routes.pngMount 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 rubbly slopes and abundant water make it prone to landslides and lahars (volcanic mudflows), especially during eruptions. Lahars are the biggest hazards to the area. Scientists and emergency officials watch and warn.

Do your part by being prepared.
