Geothermal area in the highlands
Kerlingarfjöll (1,477 m (4,846 ft)) is a mountain range in Iceland situated in the Highlands of Iceland near the Kjölur highland road. The volcanic origin of these mountains is evidenced by the numerous hot springs and rivulets in the area. And indeed, they are part of a large volcano system of 100km² (38.6 square mile). The volcanoes of the range are tuyas.
The earth is shimmering red in this area because of the volcanic rhyolite stone the mountains are composed of. Minerals that have emerged from the hot springs also color the ground yellow, red and green.
