America’s Volcanoes Are Losing Their Ice — And One Is in Trouble

America's most dangerous volcanoes aren't erupting — they're melting. This video reveals how Mount Rainier, Mount Baker, Glacier Peak, Mount Hood, and Mount Shasta are losing glacier ice faster than ever recorded, and why that puts nearby towns at risk of deadly lahars (volcanic mudflows) even without an eruption. We break down real USGS data, the 2024 Mount Hood glacier study, Mount Rainier's Tahoma Creek outburst floods, and the science debate over glacier retreat and rockslide danger. Learn which volcano is most at risk, how scientists detect mountain collapses, and what people living near Cascade volcanoes should know about lahar hazard zones and evacuation routes.
