Krýsuvíkurberg is one of the biggest bird cliffs in Iceland, stretching 8 km (5 miles) and up to 60 meter high (200 feet). The cliffs are home to up to 60000 pairs of seabirds, with the biggest population Kittiwake, then Common Guillemot and Razorbill. In the picture the lava lines are very clear and good example how Iceland was built up layer by layer of lava for the last 16 million years and still going strong.
