Mývatn is a volcanic lake in northern Iceland. The name of the lake (Icelandic mý ("midge") and vatn ("lake"); the lake of midges) comes from the huge numbers of midges to be found there in the summer.
The lake was created by a large basaltic lava eruption 2300 years ago, and the surrounding landscape is dominated by volcanic landforms, including lava pillars and rootless vents (pseudocraters).
The Steam rising in the background is from Natural Geo-Thermal vents. which gives the whole area an otherworldly feeling.
Dettifoss is located in Vatnajökull National Park in Northeast Iceland. The water comes from the Vatnajökull glacier and is sediment-rich, colouring the water a greyish white. The Jökulsá á Fjöllum river falls for more than 44 metres, causing a massive, crashing spray and creating this marvel of nature.
In Icelandic folklore, Dimmuborgir is the home of a troll named Grýla, her third husband Leppalúði and their sons The Yule Lads.
