Mt. Saint Helens has been pretty active since it's eruption. You can see inside the crator that it has been building up a new peak. Interestingly enough, that peak contained the only glacier in the world that was growing, instead of receding. It looks like the new peak to the Moutain won't last too long.
Don, if you haven't yet seen the IMAX film on the Ring of Fire, I highly recomend it.
