Drilling 460 meters to bedrock, a scientific team led by Lonnie Thompson, a professor of geological sciences at Ohio State University (OSU) in Columbus, Ohio, has produced the longest ice core ever taken from a mountain glacier. The core, from an ice cap between Mount Bona and the Churchill stratovolcano on the Canadian‐U.S. border, beats by 150 meters the previous record for a glacier ice core. This was from the Guliya ice cap in western China, also drilled by a Thompson‐led team.
