The Námafjall Geothermal Area or Hverir is located in Northeast Iceland, on the east side of Lake Mývatn. In this area, also known as Hverir, you will see many smoking fumaroles and boiling mud pots, surrounded by sulphur crystals of many different colours. This sulphur gives the area an overwhelming smell of eggs.
The terrain and the scenery are very surreal. The cracked ground boasts red, green, yellow, and white shades. The steam slightly obscures the barren surroundings. There are several impressive features that make a trip to Namafjall Hverir geothermal area incredibly worthwhile.
The soil in the area has little vegetation due to the acidity caused by these geothermal processes. Mud pots form in high-temperature geothermal areas where there isn’t much water. They gurgle and bubble slightly outside their craters, leaving grey and white slurry around the edges.
Fumaroles are the most intriguing element of Hverir geothermal area. These openings in the earth’s crust emit sulfuric gases. Fumaroles often exist in volcanic regions along cracks or fissures in the ground. It’s almost hypnotizing to watch the clouds of smoke emanating from a steam vent.
Hverir really does feel like stepping foot on Mars or another planet. It’s no wonder that American astronauts used Iceland as a training ground to prepare them for travel to the Moon.
