A view looking out from the preliminary base camp on the Mount Bona-Mount Churchill col and upslope to nearby Mount Churchill, a huge ancient stratovolcano. Ohio State University researchers will attempt to retrieve ice cores through the ice cap to bedrock in hopes of capturing a history of climate trapped for thousands of years in the ice.
