Gjabakkahellir was formed by flowing lava that cooled into a tube before the eruption was complete more than 9,000 years ago. In geological time, that’s a baby. In human time, that’s around when agriculture was really taking off. In Iceland time, that’s long before anyone had set foot on the island but birds.
We got to go through the tube, which is a little over 300m, twice in a week in late July/early August!
These videos are from the first time we went, with a bunch of people from the place we’ve been volunteering all summer. A great memory!
