It's been said before, and it is true, that Iceland's surface looks to many as the Moon's surface. And quite so indeed, particularly in this shot. This is the longest lava cave system discovered here, the Surtshellir caves, ca. 2 km long.
Being of volcanic origin, the interior walls are composed of vitrified layers of magma and basalt. The roof of the cave is about 10 meters high at the highest point, and the tunnels are around 15 m broad at their greatest width.
In the 10th century, the cave and the passages that lead out from the main cavern were used by outcasts and bandits as hideouts. They would steal livestock from local farmers. Evidence of their existence has been found in the form of the bones of sheep and oxen eaten for food in several of the tunnels.
