This was shot at Jokulsarlon, Iceland, where icebergs come crashing down from the Vatnajokull glacier and begin their journey out to sea. Some of those icebergs, after melting down enough to escape the narrow exit to the lagoon, become trapped against the shore by the crashing waves. These three were amongst many scattered here, slowly melting away.
The icebergs take on various different colors based on the atmospheric conditions. The black one in the background is the result of volcanic ash frozen into the ice.
