People who were around at the time probably remember when Mount Saint Helens in Washington State erupted in 1982. This is what it looked like on March 9, this year. The depression on the flank of the mountain is still quite noticeable, though it is covered by thick snow. This whole area of the mountain was blown away during the very powerful eruption.
The mountain is still active, though quiescent, but it looks quite peaceful in the picture. This is now a national monument.
