Floating on Air

If you look closely, in the center of the image, on the horizon, you'll see an island that seems to be hovering just above the water. Bigafying the image, by clicking on it, will help.

Here's a crop, with the floating island again in the center on the horizon. Bigatficaiton will no doubt help here as well.

A mirage, caused by temperature variation at different heights in the air above the water, which in turn changes the index of refraction, which causes the light rays to bend. Turning the real into the wondrous.

At least it does for me.
