Untitled Page Our favorite volcanologist is back! Come and join Dave as he talks about the volcanic history of Mount Baker: eruptions, collapses, and the range of hazards this dangerous, active volcano poses. At 40,000 years old, Mount Baker is one of the youngest volcanic cones in the Cascade volcanic arc. Very little was known of its volcanic history until extensive geologic mapping began in the mid 1990s. This work shows that Mount Baker is but the youngest in a series of volcanoes in the area, extending back over 1,000,000 years. Other volcanoes in the Baker group include a caldera, which erupted roughly 200 times as much ash as Mount Saint Helens did in 1980, all in a single devastating eruption. Work continues to describe and define the post-glacial eruptive history. The newest, as yet unpublished research shows that eruptions have sent minor amounts of ash northeast into British Columbia. The largest known volcanic collapse sent a large lahar down the Middle Fork Nooksack River into the lowlands of Whatcom County. At that time, this river flowed north into the Fraser past the modern site of Abbotsford, and it appears this lahar traveled that far. A repeat of this event could do the same.

The presentation will be given by Dave Tucker (MSc Geology), a research associate with the geology department at Western Washington University. Dave has been mapping Baker's geology since the mid-1990s. He is a director of the Mount Baker Volcano Research Center, a nonprofit organization that seeks to coordinate research on the volcano in our backyard, raise funds to support student and independent research, and educate the public in the hazard zones of Mount Baker.
