Volcano Mount Rainier
By many assessments the most dangerous volcano in the United States: an ice-clad stratovolcano within sight of Seattle and Tacoma. The main threat is not lava but lahars; past mudflows reached ground where tens of thousands of people now live, and the valleys below have lahar sirens and evacuation routes.
