Volcanic Steam Eruption

Volcanic Steam Eruption


Mount Saint Helens

Mount Saint Helens (external link) had been spitting steam and minor quantities of ash for several months at the time of this photo, while growing a prominent lava dome in the crater left behind by the famous 1980 eruption. Melting snow, seeping through fissures in the ash and lava, supplied water for this steam column rising off the crest of the lava dome. Here, a small finger of ash also is visible against the left (NE) edge of the dome, trailing a rockfall that is landing in front of the base of the secondary steam column. An uncommonly fair day provided ideal conditions for observing and photographing this American geologic marvel.
