Grjótagjá is a lava cave with thermally heated water in the rift zone near Mývatn where the Eurasian and American plates drift apart. In the 18th century outlaw Jón Markússon used it as a refuge, later locals and tourists bathed in it until the water got too hot during the Krafla Fires (1975-84). After the end of the eruptions the temperature slowly cooled again, but remains unpredictable. Grjótagjá (Jon Snow's cave) shot to fame with GoT, attracting masses of visitors and vandalism. The private landowners were forced to prohibit bathing in both Grjótagjá and neighbouring Kvennagjá.

in the rift zone between the Eurasian and American plates. The jump isn't quite as harmless as it looks, see note. hFF, folks!

Hverarönd (Hverir) geothermal field at the foot of Námafjall is part of the Krafla volcanic system. Find the fence....hFF folks!

View north along the Þrengslaborgir crater row towards Krafla. View south a rough bit of track

The crater rows of Lúdentsborgir and Þrengslaborgir (in the background left) erupted ca. 2300 years ago and formed the so called Younger Laxárdalur lava (total volume 2-3 km³) which created Mývatn in its present shape. The main photo is looking south with the table mountains Bláfjall and Sellendafjall in the background. The photo in the note is looking north and shows the tuff cone Lúdent which was formed in a hydromagmatic eruption at least 7000 years ago, in the foreground some of the Lúdentsborgir craters. Die Kraterreihen von Lúdentsborgir and Þrengslaborgir (im Hintergrund links) sind vor ca. 2300 Jahren ausgebrochen und haben die sogenannte jüngere Laxárdalur Lava (Gesamtvolumen 2-3 km³ ) hervorgebracht, die den Mývatn in seiner heutigen Form gebildet hat. Das Hauptfoto ist nach Süden aufgenommen und zeigt im Hintergrund die Tafelberge Bláfjall und Sellandafjall. Das PiP zeigt den Tuffring Lúdent im Norden, der vor mindestens 7000 Jahren durch eine hydromagmatische Eruption entstand, davor einige der Lúdentsborgit-Krater.

HFF everybody!

Hverarönd is a high temperature geothermal area on the eastern slopes of Nàmafjall, an active volcano in the Krafla volcanic system. Hverarönd ist ein Hochtemperaturgebiet auf des Ostseite des Námafjall, eines aktiven Vulkans im System der Krafla. I'm off to Iceland, see you in August!

Dimmuborgir (literally: dark castles) was created 2300 years ago during the fissure eruption in the Þrengslaborgir und Lúdentsborgir cone row. Because the many rootless eruptions in Lake Mývatn held up the lava flow a secondary lava pond was created that drained rapidly once the lava had made a dry pathway across the lake, leaving behind a maze of lava tubes and pillars. Dimmuborgir (dunkle Burgen) entstand vor 2300 Jahren während eines Ausbruchs in der Þrengslaborgir und Lúdentsborgir Kraterreihe. Weil der nahegelegene Mývatn-See den Lavafluss ausbremste, bildete sich ein sekundärer Lavasee, der sich schnell leerte, als der Lavafluss über den See wieder in Gang kam. Zurück blieben erstarrte Schlote und Lavagänge.

Lake Mývatn is famous for its many rootless cones (pseudocraters) which were formed by steam explosions in the Younger Laxárdalur lava flow ca. 2300 years ago. It also is a RAMSAR site due to the many duck species breeding on the lake.

Very active mudpools at Hverarönd, bubbles building up and bursting.

Dimmuborgir originated as a lava pond which drained in a very short time, leaving behind a labyrinth of pillars and caved in lava tubes.
