called Marteinsflaeda is north of Lakes Gaesavotn, and the 4wd track
there continues to Valley Bardardalur. It is divided into the
Southern and Outer Hot Springs. The southern thermal area yields more
water, 30-40°C hot, which appears through a narrow crack on the
surface. A few decades ago it was dynamited and a nice bathing pool
was the result. The outher thermal area is located at the western
edge of the Laufrond Lava Field, the main breeding area of the Snowy
Owl in Iceland.
