Research shows continued decline of Oregon’s largest glacier

September 7th, 2010



An Oregon State University research program has returned to Collier Glacier for the first time in almost 20 years and found that the glacier has decreased more than 20 percent from its size in the late 1980s.

The findings are consistent with glacial retreat all over the world and provide some of the critical data needed to help quantify the effects of global change on glacier retreat and associated sea level rise.

Flowing down the flanks of the Three Sisters in the central Oregon Cascade Range, Collier Glacier is at an elevation of more than 7,000 feet. It’s one of the largest glaciers in Oregon and is on a surprisingly short list – maybe 100 in the entire world – of glaciers that have been intensively studied and monitored for extended periods of time.
