mt st helens The southern flank and crater rim of Mt St Helens

The shape of the volcano changed drastically in the May 18 1980

eruption, as the top 600 m of the volcano collapsed and was blasted

sideways. The slopes you see here are mantled by ash from both this

and earlier explosive eruptions. This is a black and white treatment

of a colour shot taken from a Cessner 4 seater airplane.
