On March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States.A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980, at 8:32 am.
This collection consists of 235 photographs in a study of plant habitats following the May 18, 1980 eruption of Mount St. Helens. Audio recording of the May 18, 1980 eruption (audio). Recorded 140 miles (225 km) southwest of the mountain. Believed to be the only audio recording of the eruption. The Royal Geography Society's Hidden Journeys project:
Bear Meadows is an alpine meadow and viewpoint northeast of Mt. St. Helens. It is located on U.S. Forest Service Road 99. Gary Rosenquist camped here with friends on May 17–18, 1980. He started taking his famous eruption photographs from this location. The sequence of eruption photos provide a time-lapse view of the developing eruption. As ...

Virginia Dale, a renowned scientist with local ties, has again returned along with her ecological research team to sites catastrophically destroyed in the May 18, 1980 eruption of Mount St. Helens ...
Then, on May 18, 1980, the dramatic eruption of little-known Mount St. Helens shattered the quiet and brought the world's attention to the arc. Geologists were also concerned that the St. Helens eruption was a sign that long-dormant Cascade volcanoes might become active once more, as in the period from 1800 to 1857 when a total of eight erupted.
In the weeks leading up to the eruption of Mount St. Helens, Landsburg visited the area many times in order to photographically document the changing volcano. [6] On the morning of May 18, he was within a few miles of the summit. When the mountain erupted, Landsburg retreated to his car while taking photos of the rapidly approaching ash cloud. [7]
During the May 18, 1980 eruption of Mount St. Helens, Spirit Lake received the full impact of the lateral blast from the volcano. The blast and the debris avalanche associated with this eruption temporarily displaced much of the lake from its bed and forced lake waters as a wave as much as 850 ft (260 m) above lake level on the mountain slopes ...
