malformalady:

Approximately 90% of any iceberg is below the surface, making iceberg flips a rare occurrence. These photos were taken by the the U.S. Antarctic Program in Iceberg Alley, a region in the western Weddell Sea. Large old icebergs contain centuries of windblown sediment and minerals, visible as layers when they roll over as seen in the photo
