The Dragon’s Eye

At https://www.livescience.com/planet-earth/geology/norways-dragons-eye-the-fantastical-pothole-that-emerged-from-ice-16000-years-ago … the Dragon’s Eye, we are told, probably formed around 20,000 years ago, when Scandinavia was buried underneath ice. The Dragon’s Eye is a natural hollow in rocks along Norway’s NW coastline. It looks like a reptilian oculus. In addition, a boulder at the bottom of the hollow stands out against the bed of white sand and algae on which it sits, forming the pupil of the eye. It is an entirely natural feature – a glacial landform known as a pothole. The Fennoscandinavian ice sheet blanketed Scandinavia, parts of northern Europe, and NW Russia, during the Late Glacial Maximum. Glaciation can lead to weird geological formations as a result of erosion of bedrock by the glacier itself, or its run off. Indeed, meltwater is actually invoked as one possibility. Rather, meltwater currents – or lots of water movement beneath the ice. This, it is thought, can concentrate erosion in the creation of hollows or potholes.
