The icebergs calving off the Greenland icecap are some of the largest I've seen at the moment, quite possibly due to increasing temperatures. Here a traditional Schooner sails behind the arch for scale. There was some academic debate about attempting to climb it, but I think the objective danger of such a large iceberg is just too high.

Very original shot. A bit special in my opinion, perfect crop too.

beautiful. Icebergs are the giant equivalent of snowflakes - no two alike

Absolutely bonkers. Amazing image

Timing is everything or perhaps this was preplanned?

Absolute prize winner!

Never mind climbing pictures, this is one of the best pictures I've ever seen!

Colours are surreal. I'll be amazed if we don't see this photo going wider than UKC soon .. Images of the day on various digital newspapers etc.

That is a truly outstanding photograph! I wish I could give it more that 5 stars.

Thanks very much once again everyone. This image was picked up by the Guardian, Times, Telegraph and Mail Online today :) .

Have just spotted this in the Times. Absolutely stunning photo - truly fantastic.
