Dartmouth Drills at Denali to Document Climate Change

JOSEPH BLUMBERG

On June 18, Erich Osterberg left Alaska’s Denali National Park, where a collaborative Dartmouth-University of Maine-University of New Hampshire team had chronicled 1,000 years of regional climatic history.

“We drilled two 700-foot, 4-inch-wide holes to bedrock through the glacier on Mount Hunter, the third highest peak in the Alaska Range and Denali’s closest neighbor,” says Osterberg, an assistant professor in Dartmouth’s Department of Earth Sciences.  An unusual lack of storms allowed the team to complete the ice core drilling and an array of supporting field research quickly and efficiently. “Alaska’s exceptionally warm summer this year also drew attention to the shifting climate picture,” he adds.
