What the Heck Is This?

This looks a lot like the scene in the desert near my Arizona home, but there is something missing. Not going to say what, but that's a big clue.

Can you guess where on Earth this is? Or isn't? You should be warm by now, and if you were there, you'd be very cold.

Enough with the riddles. See the answer below…

It's a view of Mars, from Mars. What's missing, of course, is any sign of life. The photo was beamed to Earth from NASA's Opportunity rover this week. After almost three years, the rover reached this scene at the edge of the giant Endeavour crater.
