The second day started inside the Vatnajökull glacier in a cave, and continued with a sunrise just at the glacier edge. Now, we'll experience the glacier ice in another shape. At the south edge of the glacier, you find a lake, or rather lagoon, called Jökulsárlón. Icebergs that calve from the glacier edge slowly travel through this lagoon, out into the sea.
When watching these icebergs, I found it curious how different blocks of ice had different characteristics. Some blocks are pretty much transparent, like huge blocks of glass. Others look more like packed snow, others had a blue-green tint that made me think of tooth paste.
Some of the icebergs have streaks of black volcanic ash in them, providing some interesting contrast and at the same time revealing a little something about the geological history of the area.
