A U.S. Geological Survey climbing party ascends the Klutlan Glacier headed towards Mount Churchill. Their field studies led to the discovery that this volcano was the site of two of the most voluminous eruptions in North America in the past 2,000 years. The White River Ash originated from the summit caldera of Churchill next to Mount Bona and comprises two voluminous ash units that extend across most of Canada and traces reached Europe.
