Mt. St. Helens: 30 years later

See here three aerial images from Livescience of Mt. St. Helens before the eruption in 1979, afterards in 1980, and today.

Allison, thanks for the link to the aerial views. It is hard to believe it has now been 30 years since the big eruption! Looking back, one of the main "ecological lessons" I have gained from the 1980 eruption is an appreciation for the power of nature's recovery abilities and the corresponding importance of "natural" disturbances to landscape diversity. This is a message that is relevant everywhere, whether we are talking about volcanoes, hurricanes, or fire. There is a nice Forest Service document about the landscape "recovery" on the web at http://www.fs.fed.us/pnw/pubs/science-update-19.pdf

You're exactly right, Ed. I recall they planted a bunch of trees around the perimeter of the main blast site, a big plantation, but the natural recovery is just as expected. Unfortunately, we as a society are so quick to clean up and forge up after natural events, and so many of our disasters these days are so very far from natural....thanks for the link.
