  3. i was on holiday near yssingeux in france and bumped into a bunch of these volcano corks with columnar basalt and was amazed, and the locals made their houses out of it because it was free brick material, all the villages are around the volcano corks made from fallen basalt bricks. only question for me is where is the gold there.
