Following the May 2005 acid crater lake flood at Chiginagak volcano, DGGS has been monitoring crater lake water that flows into Indecision Creek, Mother Goose Lake, and the King Salmon River.This data table provides information on water samples collected between 2005 and 2011 near Chiginagak volcano, including:sample ID, latitude, longitude, location description, pH, and cation and anion chemistry results.
This data lists the historically active volcanoes of Alaska and the year of the last major eruptive event. The volcanoes listed meet at least one of the following criteria since 1700 CE: (1) documented, unquestioned eruption, or (2) a strongly suspected eruption, often an eruption documented in the historical account with very little information (current geologic knowledge must not contradict the eruption account), or (3) persistent (usually on the order of decades, but certainly longer than several months) fumaroles, with temperatures (where measured) within ~10 degrees C of the boiling point, or (4) significant, measured, volcanic-related, non-eruptive deformation, (5) documented earthquake swarm with strongly...

Index card: On Coldwater Ridge, ash is about 18 inches thick. Geologist in trench for scale. Skamania County, Washington. 1980.
Index card: Three other Cascade volcanoes are visible from Mount St. Helens - Mt. Adams to the east. Any one of these Cascade peaks has the potential for becoming another active volcano. Yakima County, Washington. September 23, 1983.

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.
