I visited Hawaii Volcanoes National Park recently, with friends from the mainland, and towards the end of our visit we stopped by Thurston Lava Tube. These days the tube is known as Nāhuku, which means “the protuberances” in Hawaiian. There aren’t any protuberances in the tube these days, but it’s still fun to walk the dimly lit tube, imagining magma rushing through it, until the eruption stopped and the tube drained.
