Guide to Aldeyjarfoss Waterfall in Iceland

Aldeyjarfoss is a waterfall located in the northern part of Iceland, near the Sprengisandur highland road. It is situated in the Skjálfandafljót river, known for its powerful and scenic waterfalls. Besides Aldeyjarfoss, Skjálfandafljót River holds the well-known waterfalls Hrafnabjargafoss and Goðafoss. The Skjálfandafljót River is the fourth longest river in Iceland, spanning a total of 178 kilometres (111 miles). It is a glacier river sourced from the largest glacier in Europe: Vatnajökull.

Aldeyjarfoss is distinctive in the contrast between the black basalt columns surrounding the waterfall and the white water cascading over it. The basalt columns are hexagonal in shape, creating a visually striking and geometrically exciting backdrop for the waterfall. This geological formation is a result of the cooling and contracting of lava.

Geological Features of Aldeyjarfoss

Aldeyjarfoss, with a height of 22 metres (72 feet), gracefully descends into a captivating blue lagoon. Its renowned allure lies in the surrounding geological marvels. Flanking the waterfall on either side are rows of impeccably formed hexagonal basalt columns, a feature scarce in global landscapes.

The symmetry of these columns, resembling meticulous hand-carving, finds its explanation in physics. Centuries ago, lava flowed down the cliffs at Aldeyjarfoss during a volcanic eruption that took place in the central Highlands near Vatnajölkull. As the lava flow cooled and solidified, the columnar jointing took place. This process occurs when molten lava solidifies and contracts as it cools and forms hexagonal columns.

Similar basalt formations grace other locations in Iceland, such as the Gerðuberg cliffs on the Snæfellsnes Peninsula and the cliffs in the village of Hofsós. However, the only other easily accessible waterfall featuring these columns is Svartifoss in the Skaftafell Nature Reserve in the southeastern part of the country.

Notably, Aldeyjarfoss boasts a more diverse colour palette for its columns compared to its black counterparts at Svartifoss. Yellow and red hues, attributed to sulphur and iron brought up during the eruption, enrich the visual tapestry of these geological wonders.

Glaciers, Rivers and Waterfalls

Iceland is known for being the country of fire and ice. The island has been formed and is constantly changing due to active volcanoes and glaciers melting. Aldeyjarfoss is a result of the interaction between lava and the glacier river. Visit the Perlan Museum in Reykjavík and learn more about the forces of nature. The Glacier interactive exhibition provides insight into Icelandic glaciers, their bleak future, and the effects of climate change.
