Mount St. Helens commemorates an explosive 25th anniversary

That white plume issuing from Mount St. Helens's crater: Is it asign of surrender? Hardly. It was 25 years ago the morning of May18 that the once-dormant volcano erupted, radically altering thesurrounding landscape and its own profile. Since September 2004,when a swarm of shallow earthquakes began shaking the mountainagain, the crater has been steaming regularly, some days more thanothers, and even throwing clouds of ash, to the awe of volcanowatchers at the 110,000-acre Mount St. Helens National VolcanicMonument.
