Tour around Kilauea Crater: Stop 7

About 350 - 500 years ago, Kilauea Caldera was much smaller than it is today, or it may even have been full of lava flows. At that time, lava streaming from the summit created this lava tube (called the Thurston lava tube), which is about 4 - 5 meters high. The official part of the trail along the tube is only a few hundred meters long, but the lava flow in which it was created extends almost 40 km from the vent.
