The History and Science of Glacier Change in Western US and a Peek into their Future

The Pacific Northwest is home to the most glaciers anywhere in the continental US. And we take glacier observations for granted, we know somebody is looking at them. But I got to wondering, when did glacier observations start and who started it? When did science discover glaciers here in the West? The history is surprising and the glaciers in Oregon played a major role. The cast of characters includes the famous and not so famous, and controversy brewed for more than a decade. And part of the controversy included, 'What is a glacier?'. Since their 'discovery' glaciers have been observed off and on since the start of the new century in 1900, mostly by amateur hiking clubs. These early observations have provided key data in understanding about how the glaciers have changed over time. While they are all retreating generally, there is one major exception, a new glacier, less than 50 years old. Sadly, however, their future is grim.

Dr. Andrew G. Fountain is a professor of Geology and Geography at Portland State University where he has conducted glacier research for the past 25 years. Prior to that he was a glaciologist with the US Geological Survey in Tacoma, WA and Denver, CO. His studies have taken him to Antarctica, Alaska, Arctic Sweden, and the western U.S. Greenland may be in his future. His studies on the glaciers of the American West can be viewed at www.glaciers.us


In accordance with the continuing evolution of Governor Brown's executive orders, we have suspended field trips through June 2020.
