After breakfast I went for a quiet walk along an official footpath – the moss is very damageable and a few too many people trampling over it can destroy within days what nature has created in years - through this mystic labyrinth and then hit the road again, but only for a few minutes.
The landscape was changing now, and I reached the Álftaver area. It still is a generally flat area of alluvium, with a bit more of vegetation and generally rather dreary. Actually not really worth mentioning if there wouldn´t be these strange bumps scattered over the plain.
These bumps look like mini volcanoes but are pseudo-craters, or "gervigígar" in Icelandic. They develop when lave flow over water-soaked soil and the water superheats and forms steam that cannot escape from under the lava. Once the steam pressure exceeds the overlying burden of the lava, it pushes its way to the surface with great explosions and a pseudo-eruption begins that forms these molehills. The result is another landscape that leaves you scratching your head.
