Topic: The presentation will include a description for how tree-ring dating in Cascadia has contributed to a better understanding of some significant pre-historical geologic events. We'll examine clues from Indigenous stories, Lewis and Clark, and tree-rings about Mount Hood’s most recent eruption and the Bonneville landslide in the Columbia Gorge. Then we'll examine a reanalysis of Mount Rainier’s recent history of eruptions and lahars, with lessons learned at Mount St. Helens. And finally, we'll look at how landslide-dammed lakes dated by drowned trees have helped date past earthquakes in an around Seattle.
