The well-rounded iceberg in the picture looks like it has been floating around for a while, and has turned at least partially over before, based on how rounded it is. Possibly this is a bergy bit, not an iceberg, the difference being a bergy bit (piece of ice broken off an iceberg) shows less than 5m/15′ above the surface of the water. Amos, that is a great poem (in the comments to an earlier post). Thanks for sharing it.
