Mt. St. Helens has started erupting again, and I am on the wrong continent to follow it, but the forestry service has a webcam at the Johnson Ridge Observatory that let's you see the latest pictures from the volcano.
I went to the Johnson Ridge Observatory with Kate's class a couple of years ago. It is one of those places that gives you a sense of the power of the volcano. One of the rangers pointed out a discolored piece of rock on a hillside about 8 miles from the volcano. He said that the discoloration was actually a large piece of the top of Mt St Helens which was blasted all the way over there during the 1980 eruption.
Johnson Ridge is definitely a great place to visit -- but not today.
