 Stunning display of an iceberg, drifting at sea.

Stunning display of an iceberg, drifting at sea.

Stunning example of an Antarctic iceberg. While the natural bridge just makes you want to cruise right under it, due to the unpredictability of icebergs, it's a big no-no safety wise. The 'berg could roll or breakup without any warning and there would be no time for a quick escape.

I guess it's the kind of thing you'll eventually see on a GoPro video somewhere. After all, there was a GoPro video of a couple guys climbing an iceberg that helped launched the Hero4. Cool as that video is, a pretty brazen thing to do.
