A bay to the north of Fuerteventura, famous for the surf and the sound the waves make on the incoming tide- the sea dashes against the loose boulders, rocks them around, and makes a loud echoing sound like thunder, quite fascinating! (2006)
Now the picture is enlarged, I've just noticed that the sea appears to be sliding sideways! Must have been an extra effect of the rolling rocks!
Lovely shot. Great movement.
