Jökulsárlón

A lagoon that did not exist before the 1930s: Breiðamerkurjökull began retreating in the late nineteenth century and the meltwater filled in behind it. It now covers about twenty-five square kilometres, four times its size in the 1970s, and in 2009 was reported the deepest lake in Iceland at over 284 metres. The glacier front stands some eight kilometres back from the sea. It is the largest and most active glacial lake in the country, and the icebergs calving off the outlet have been described as a ghostly procession of luminous blue.
