Lava Skylight - John Seach

A skylight is an opening in the roof of a lava tube. Skylights usually form when part of the roof collapses into the tube,
but they also occur where a roof failed to form over the lava channel. If the tube is active,
a stream of glowing lava can be seen moving below. Skylights are common at Kilauea Volcano, Hawaii.
