Ride 'em Turtle
There's a turtle in that picture above. Even if you click on it and look at it full size, the turtle's not easy to see. In fact, you can just barely see the waterlogged stick that he's riding.
In the picture below, where I zoomed in on him, it's a little more obvious what's going on. Still, what turtle in its right mind is going to be riding a stick that's moving at a good clip in a strong April breeze?
It's not obvious in the picture but that log that the turtle is perched on is in the middle of a bay and moving along at about a normal walking pace. The turtle was effectively acting as a sail, allowing the wind to move the branch a lot faster than the water it was in.
