Lava Tube

Big Island, Hawaii

This lava tube is a relic from an old volcanic eruption that poured large amounts of lava into the sea, but also left a giant tube that travels hundreds of yards into the ocean. It creates an intriguing if dangerous situation as waters erupt from the tube with each wave only to be sucked down in an instant as the wave retreats. Photo © copyright by Ed Fuhr.
