A towering columnar basalt cliff is partially reflected in the waters of Breiðasund in the town of Stykkishólmur, Iceland. Columnar basalt is a volcanic rock formed when basalt lava rapidly cools at or very near the Earth's surface. Basalt, which is naturally grey or black, is rich in iron and can rapidly rust, taking on a reddish-brown appearance.
