Svartifoss (Black Fall) is a waterfall in Skaftafell in Vatnajökull National Park in Iceland, and is one of the most popular sights in the park. It is surrounded by dark lava columns, which gave rise to its name. Other well-known columnar jointing formations are seen at the Giant's Causeway in Northern Ireland, Devil's Tower in Wyoming, USA and on the island of Staffa in Scotland. There are also similar formations throughout Iceland, including a small cave on the beach of Reynisdrangar.
The base of this waterfall is noteworthy for its sharp rocks. New hexagonal column sections break off faster than the falling water wears down the edges. These basalt columns have provided inspiration for Icelandic architects, most visibly in the Hallgrímskirkja church in Reykjavík, and also the National Theatre.
As of 2019, Vatnajökull National Park is a Unesco World Heritage Site. This iconic volcanic region covers an area of over 1,400,000 ha, nearly 14% of Iceland's territory. It numbers ten central volcanoes, eight of which are subglacial. Two of these are among the most active in Iceland. The interaction between volcanoes and the rifts that underlie the Vatnajökull ice cap takes many forms, the most spectacular of which is the jökulhlaup – a sudden flood caused by the breach of the margin of a glacier during an eruption. This recurrent phenomenon has led to the emergence of unique sandur plains, river systems and rapidly evolving canyons. Volcanic areas are home to endemic groundwater fauna that has survived the Ice Age.
