Its height is about 855 m. It is situated near Landmannalaugar and not far from Hekla.

The name means in English: sulphur wave.

But there are other colours, too: green from mosses, black and blue from lava and ashes, red from iron in the earth.

It could very well be the most colourful mountain of Iceland and so its picture is often found in books and calendars.

The mountain is still visibly an active volcano with hot sulphur springs and vapour at its sides.
