Búrfell Mountain and Þjófafossar Waterfall- South
Búrfell (Þjórsárdal) is a 480 m (1,570 ft) basalt tuya located in Iceland. It is situated in the south of the country along the western boundary of the Þjórsárdalur valley.
The mountain is a basalt tuya, with tuya being a type of volcano formed when lava erupts through an ice cap or a glacier. These mountains are recognisable by their distinct shape of a flat top and steep sides. Such mountains are rather rare worldwide, confined to areas where active volcanism is occurring at the same time as glacial coverage. Lava which erupts under a glacier cools relatively quickly and is restricted from travelling far, so as a result, the lava piles up into a steep-sided hill.
The river Þjórsá runs to the east of the mountain and to its south lie the waterfalls Þjófafoss and Tröllakonuhlaup that feed into the river. Þjórsá has been harnessed for its energy and the resulting power station, Búrfellsvirkjun, was named after the mountain. This hydroelectric plant, which started its workings in 1972, was the first grand-scale construction of its kind in Iceland and marked the beginnings of local industrialisation of natural resources.
At the foot of Búrfell stands the Viking museum Þjóðveldisbær, a reconstructed farmstead of historical accuracy, which includes a traditional Viking longhouse.
There is a lot of different mountains in Iceland by the name of Búrfell, f. ex. Búrfell (Grímsnes), Búrfell (Þingvellir) and Búrfell (Mývatn).
The Icelandic word búr means cage or pantry in English.
