Iceland mal Lake Mvatn

Lake Mývatn was created by a large basaltic lava eruption 2300 years ago.

This lake is situated in an area of active volcanism in the northern Iceland. The surrounding landscape is dominated by volcanic landforms, lava pillars and pseudo craters.

Iceland Lake Ball Mvatn stamp timbre Briefmarke francobolli

Iceland 2008, Lake ball.  

Lake ball (Aegagropila linnaei), also known as Marimo, is a rare species of filamentous green algae found in a few lakes in the northern hemisphere. Colonies of such balls are known only in three lakes, Myvatn in Iceland, Lake Akan in Japan and to a much lesser extent in Lake Öisu in Estonia. Around 5000 people live at Lake Akan in Japan where tourism is the main industry with lake balls constituting the main attaction. The lake ball is a protected species and considered a rare natural phenomenon. Each year around 500.000 tourists visit Lake Akan and a special Lake Ball Festival is held each year in autumn. The species has three different growth forms, lake ball being one of them reaching up to 10-20 cm in diameter. Until recently scientists in Japan thought that the batches of lake ball in Lake Akan were the only ones known in the world. It is a remarkable fact that two such rare and similar communities of algae should be found so far away from each other. The lakes in Iceland and Japan still have something in common. They are situated in highly volcanic areas with geothermal heat in the banks of both lakes. Lake ball has been protected as a nature reserve in Iceland since 2006. (text: Iceland Post)
