This image has apparently been all over the Internet/blogosphere, but, well. . . wow, worth putting here as well.
This is Tahiti’s Teahupoo break, apparently one of the steepest (and most dangerous) waves on the planet.
You fall, you die. That sort of thing.
Wonder if this was shot with a GoPro camera?
Here’s a full-screen shot of the wave: www.ferket.com
Thanks to The Goat for bringing it to my attention.
