I received this by e-mail, and it looks like the photos are from the blog Yacht Maiken. Check them out, pretty neat.
The yacht "Maiken" was traveling in the south Pacific when the crew came across a strange sight. It looked as though sand was floating on top of the water, until the realized it was volcanic stone.
Look at these photos of this rare phenomenon. This is not a beach, it is volcanic stone floating on the water.
The trail left by the yacht, through the volcanic stone.
And then this was spotted, just behind them; ash and steam rising from the ocean.
A brand new island formed.
