Krafla

"Krafla is a tuff mountain north of Námafjall. Considerable geothermal heat on teh west side of Krafla with fumaroles and mud-springs (solfataras). At the northwest side is Víti ("Hell"), an explosion crater, 300 m in diameter with green water in the bottom. Leirhnjúkur ("Clay Peak"), is west of Krafla and on the souteast side is Hrafntinnuhryggur ("Raven Flint (i.e. obsidian) Ridge") where pure obsidian is to be found. Construction of a geothermally powered electric plant started in 1974. Its first stage has been completed and provides 30 MW. From 1975-84 there was a series of tremors and eruptions in the area, 9 eruptions altogether along a 7,5 km long fissure. These originated in the old volcano Kröfluaskja."

"Námaskarð is a narrow pass between the mountains Námafjall and Dalfjall."

"Námafjall is a mountain south of Námaskarð, with geothermal heat all over the east side of the mountain, which looks light yellow from a distance. Sulphur was mined there for centuries from the Hlíðarnámur mines and exported."

"Trölladyngja (1.459 m) is the greatest shield volcano in Iceland, about 10 km in diameter and rising 500-600 m above the surrounding area. The crater is 1.200-1.500 m long, 500 m wide and 100 m deep. Lavaflows are thought to have run down the Bárðardalur valley."
