This photo shows an outcrop of pyroclastic flow deposits near Willow Creek on the Pumice Plain at Mount St. Helens. The dramatic lines crossing the outcrop indicate contacts between different layers of pyroclastic flow deposits. Two participants of the 2019 GeoGirls program are shown studying the outcrop, using it to understand the eruptive history of the volcano.

GeoGirls hike to Willow Creek, on Mount St. Helens’ Pumice Plain, to learn more about the ecology of the blast zone and how the area has recovered since the catastrophic May 18, 1980, eruption. Here, they look at stream characteristics and how it has influenced the return of life to the area.

The GeoGirls visit a volcano monitoring station on the east side of Mount St. Helens, finding out how scientists use different monitoring methods (seismic, GPS, tiltmeter) to understand more about the volcano.

A field team from the USGS Cascades Volcano Observatory discuss station maintenance plans on the north side of Mount St. Helens, Washington. Pictured in the center of the crater is a steaming lava dome from the 2004-08 eruption, and the fractured surface of Crater Glacier emerging from the gap on the north flank.

Aerial view of Spirit Lake (center) looking north from above the crater of Mount St. Helens. The lake's outlet to the west (left) was blocked by the 1980 landslide, which required a new engineered outlet to maintain the lake at a safe level. A tunnel was drilled through a bedrock ridge on west side of lake in 1984-1985. Glacier covered Mount Rainier in distance.

Between August 19-22, 2017, 140 seismometers were deployed around Mount St. Helens. Instruments were placed on top of the 2004-2008 lava dome, the 1980-86 lava dome, the 1980 crater floor, and around the volcanic cone.
