Sunset on the crater rim and flanks of Mount St. Helens, with Mount Adams in the distance.

Crater and 1980-86 lava dome of Mount St. Helens, ash covered areas are grey, and new vent is the depression in lower center of photograph. Spirit Lake is in the background. View toward the north.

Beginning of plume above Mount St. Helens dome, as seen from Johnston Ridge Observatory.

Ash, erupted from the early phases of the 2004 Mount St. Helens activity, is remobilized from the surface of an ash-covered from a moving vehicle.
