Jökulsárlón iceberg lagoon, in Iceland, is located at the eastern arm of the Vatnajökull glacier, Europe's largest glacier.  It's the spot where large pieces of the glacier break off  into the water, then cue up to shoot down a small river into the broad ocean to be re-born as icebergs in the North Atlantic.  The water and ice are of an unimaginable shade of blue, and the line between earth and sky blurs, as you stand there watching the icebergs ebb and flow with the current.
