volcano
The mountain itself
The volcano is covered by solfataras and fumaroles . At its foot there are high temperature areas both on the west side towards Reykjahlíð and on its east side towards Ódáðahraun and Möðrudalsöræfi .
Marked hiking trails lead up the mountain. From the top you have a good panoramic view, not only of the solfataras and fumaroles in the area, but also of Lake Mývatn and the Möðrudalsöræfi desert.
Bjarnarflag geothermal power plant
In the high temperature area on the west side you can find the small geothermal power plant Bjarnarflag , which was the first geothermal power plant in Iceland. You can recognize it by the intense turquoise overflow lake, in which people used to bathe when it was less hot. Behind the also steaming chain of craters Jarðbaðshólar , approx. 2 km from Bjarnarflag, there is an outdoor swimming pool that uses the hot water in the area: Jarðböðin .
Hverarond high temperature area
It is one of the most famous high temperature areas in Iceland.
Hverarönd is located on the east side of Mount Námafjall at the Námaskarð pass , over which the ring road from Mývatn to Egilsstaðir runs.
In the high temperature area there are solfataras, i.e. places where water vapor, hydrogen sulfide , elemental sulfur and other minerals escape from the earth, as well as numerous slowly or violently boiling mud pots and fumaroles.
In literature and travel guides, the high-temperature area is sometimes referred to by the name of the mountain and sometimes by that of the pass, but the solfatarean field is actually called Hverarönd .
In the Middle Ages, the elemental sulfur was exported for the production of gunpowder . This export via the port of Húsavík continued into the 19th century.
In 1000 m depth temperatures were measured in excess of 200 ° C.
