Skamania County, Washington. 1980. These slides of the July 22, 1980 eruption of Mount St. Helens. Jim Vallance was in a U.S. Forest Service fixed wing aircraft and Mike Doukas, Harry Glicken, and Rick Hoblitt who were in a U.S. Geological Survey helicopter. There were three major eruptive pulses on July 22, 1980. They begin at 17:14, 18:30 and 19:02 PDT. 19:35 approximately; Don Swanson examines a new pyroclastic flow deposit.

Skamania County, Washington. 1980. Slide description and index card: Aerial photographs of the lava dome that extruded into the crater of Mount St. Helens during the latter part of June 1980.The volcano's dacite lava has a pasty consistency when it is molten, and it tends to pile up rather than to flow laterally. This dome, which was largely destroyed in a subsequent eruption on July 22, 1980, was, at this stage, about 1,200 feet across and 200 feet high. Its rough, shattered appearance resulted mainly from the expansion and shattering of the solidified outer crust as more molten lava was forced upward by the great pressure in the magma chamber underlying the volcano.
