This lava tube is about 1,360m long, 10-30m wide and up to 10m high. The average thickness of the ceiling is about 12 metres. On one point the road crosses the cave and the ceiling is much thinner. The traffic destroys the lava and so the ceiling becomes thinner and thinner. Probably it will become necessary to sustain the road in the future.
The cave is a ice cave of the cold trap type. All openings are going up to the surface, so cold air flowing downwards into the cave is trapped. The cave is famous for its ice formations, but also for many lava formations.
The lava field in which the cave is situated, was formed during a fissure eruption around the year 1000. It belongs to an 11km long crater row.
