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.

Caption: Huge crater left by Mount St. Helens eruption. The May 18, 1980, eruption of Mount St. Helens volcano in Washington State produced a crater at the mountain approximately one kilometer wide and two kilometers long. According to U.S. Geological Survey scientists, the atom bomb-like force of the main eruption also exploded out about 5,000 feet of the north face of the mountain and leveled trees in a 185 square mile area. The volcano last erupted 123 years ago. PIO No. 80-179.

Caption: Mount St. Helens levels 185 square miles of forestland. Thousands of trees knocked down by the atom bomb-like blast of the May 18, 1980, eruption of southern Washington state's Mount St. Helens volcano are shown in this photo taken near the mountain several weeks after the main eruption. According to U.S. Geological Survey scientists, the Cascade Mountain Range volcano's first eruption in 123 years leveled trees in a 185 square mile area and spewed about 1 cubic kilometer of ash and rock which fell over 11 western and central states. August 1980. PIO No. 80-180c
