hile on an expedition to Antarctica, Alex Cornell was stunned when he spotted an ‘alien’ blue iceberg floating across the landscape. Unlike the icebergs around it, the surreal sleeping beast was completely free of snow and debris, revealing a polished azure surface. What Mr Cornell witnessed in Drake Passage was an incredibly rare phenomenon; a flipped iceberg caused by an imbalance in frozen water.
