While on an expedition to Antarctica last month, photographer Alex Cornell witnessed a massive iceberg flip, revealing a strangely translucent blue underside that’s completely free of snow and debris. According to Science World, almost 90% of any given iceberg is below the surface, making iceberg flips extremely rare. Much larger iceberg flips are even capable of causing tsunamis that can overtake nearby ships. You can see more photos from Cornells trip on his website.
