Following excerpt from
"Volcano: The Eruption and Healing of Mount St. Helens"
by Patricia Lauber:

"On May 17, 1980, Mount St. Helens, as seen from Coldwater II, had a soaring, ash-stained peak and green forests climbing its slopes. The next day the big eruption tore the top off the mountain and flattened the forests, as shown in the September 9, 1980, photograph taken from the same place at Coldwater II."
