Alien World

These images are from a place in Arizona called White Pocket. A very ordinary name for a very extraordinary place. In all my travels I'd never seen anything like it.

At first, it was hard not to believe that these formations were the calling card of aliens and UFO's. Turns out these "brain rocks" as they're called are nothing more than petrified sand dunes, which almost came as a let down.

Nevertheless, as photography subjects, they were without equal. I spent hours exploring the area. Then, way in a far flung corner, I found this spot where these little round pebbles (called moqui marbles) had been driven into the cracks in the brain rock by the wind.
