Scientists have completed another season of ice core collection on the Mt. Hunter plateau. The team of four, from Dartmouth and Colby Colleges, spent three weeks in the Alaska Range extracting samples. While the consistent sunny skies made it easier for winter camping, warm temperatures were challenging for drilling and preserving the ice core samples.
