Iceberg at Devil Island

I love the shade of blue you find in icebergs, it's like nothing else I can think of. This is an amazing example of a 'berg that has rolled - when the sea wears away at the bottom section of the iceberg, smoothing it out, it decreases the mass which is under the water. This shifts the centre of gravity and eventually the top weighs more than the bottom and the whole this rolls sideways. Sometimes they flip completely, and sometimes they just tilt. On this one the smooth section was once under the water, but now sticks out from the top because the berg has rolled.
