The new Landsat 7 satellite is now taking high resolution images of the Earth. This 1999 press release picture shows Mt. St. Helens. The green is forest and fields, the white is glaciers and snow, and the grey shows areas destroyed by flowing ash in the 1980's eruption that have still not recovered their vegetation covering. Spirit Lake is still partly covered by floating logs. Image by EROS Data Center, Sioux Falls, SD.

Mount St. Helens is a stratovolcano. When Mount St. Helens erupted on 18 May 1980, the top 1,300 ft. disappeared within minutes. The blast area covered an area of more than 150 sq. miles and sent thousands of tons of ash into the upper atmosphere. Image taken on 10/16/94 from the Space Shuttle.
