Great sequence of Mt. St. Helens

NASA's Earth Observatory web site features interesting views of the Earth from space. They have images from space of Mt. St. Helens since before the 1980 eruption. On the following page they overlay each year from 1979 to 2010. Click on the year number below the image to see how it looked in that year. Unfortunately the earlier images are false colors - what is green shows as red. http://earthobservatory.nasa.gov/Features/WorldOfChange/sthelens.php Also read the text below the image for their description.
