This photo was taken in Hawaii Volcanoes National Park of the Thurston Lava Tube, which is open to the public to explore. It is the remnant of the tube the carried the lava from the volcanoe to the sea. It is about 10-12 feet in diameter and an interesting walk.
This is another view, using Poster Edge, Twirl and Glass filters.
Thought of saving it for Holloween, but decided to let it out now. It is lit only by the lamps, which are spaced along the wall.
Enjoy!
