Location: Central southern highlands of the Torfajökull volcanic system.
The vivid colors found in the rugged highlands of the Torfajökull volcanic system come from geothermal activity, silica-rich volcanic rocks and alpine vegetation. The brilliant blue-green color is a striking example of rock transformed by geothermal activity.
