Down on the shore, crashing Atlantic breakers are exposing fresh cliffs of pillow basalt, volcanic lava that has erupted under the sea and been rapidly quenched so that it forms features that look a bit like black toothpaste squeezed from a giant tube. This is a young landscape. The most recent eruptions here occurred in the 13th Century and there could be new ones at any time. Iceland is unusual geologically in that it exists above the ocean at all.
