Lava tube

Posted by
Harry (Apex, NC, United States) on 21 March 2017 in Landscape & Rural and Portfolio.

A lava tube is formed when the crust hardens but the lava below continues to flow. They are actually pretty common. There was one in the Park that was "groomed" with a walkway and lights that was big enough to drive a bus through. Most are smaller and dangerous... there is always the risk of collapse, and many have poisonous gases that require advanced breathing gear.

But the plants soon begin to grow to break down the lava and form new land.
