This is a northern point on Isla Robinson Crusoe, 400 miles off the coast of Santiago Chile. I was mousing over the highest point of the surf (in the foreground) when I took the screen shot. The bottom of the shot says 460 ft elevation for that spot. Click on the image below for a larger size view. That's some powerful wave action!!

Where did you get this?

It seems counterintuitive for a convex surface presented to the waves. I could more readily see it happening with a concave surface, like a fjord, etc.

Maybe the underwater bit is concave, driving the wave on that hillside
