For 123 years Mt. St. Helens in Washington state had been relatively quiet. -- Then, in 1980, rumblings began, leading to a cataclysmic eruption that sent a plume of hot gas and ash some 19,000 meters into the air. Take high school students through the geophysical events that occur during an eruption with this activity kit. -- Includes: actual ash samples from the 1980 eruption and a 96-page teacher's guide with 16 classroom-tested activities, teacher information and reproducible worksheets.
