The editors at PC World spent some time using Google Earth to scour the surface of the planet, and they turned up some incredibly strange sights. The giant portrait of Oprah cut through a field by an Arizona farmer is one thing – you almost expect something like that – but the apparently natural phenomena are the truly mind-boggling ones. The image at left, for example, is an overhead view of a natural geological formation in Alberta, Canada. Locals call it The Badlands Guardian, but based on the ear phone, I'd prefer something more along the lines of The Early Adopter. And is it just me, or does that look like Sigmund Freud sitting atop the Guardian's head?
