Svartifoss Svartifoss (Icelandic for "black waterfall", [ˈsvar̥tɪˌfɔsː]) 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. 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.

Underwater waterfall Mauritius Mauritius provides a stunning illusion just off the shore of Le Morne, on the island's southwest coast. The sand and silt on the ocean floor rush down in such a way that it appears as if they're pouring down a waterfall — or as if the entire island is being sucked into a massive sewer.
