We made several stops at Hawai’i Volcanoes National Park, the first was at the active crater. Our first stop was at the new Halema’uma’u Vent. The smoke plume behind the group comes from this vent.
The Thurston Lava Tube is named after a local haole, Lorrin Thurston (also the newspaper publisher and a leader in the overthrow of the Hawaiian monarchy). Mr. Thurston discovered the tube in 1913, and it is over 400 years old. Lava tubes are channels created during lava flow, that then serve as conduits for additional lava.
Another stop was at a deep crater, Puhimau. There was a short walk from the road to the overlook, with the trees suddenly opening to reveal the massive rock wall on the other side. It was a dramatic sight, and many gasps were heard. This crater creates an echo, and a few students tried it out.
