THIS LOOKS like a collapsed building. A real disaster much have hit it. BUT - - it is on Mars. The picture was found in the "Giga-pan" panorama photos taken by "Rover", and it was at quite some distance from the "Rover". Maybe it was destroyed in the Nuclear disaster ? Well, we know there was one. Air samples on Mars show that the atmosphere on Mars have ZENON gas in it. That is a gas that can only exist after a Nuclear discharge - - and there is much of it on Mars.
