Re: interesting Martian photos
Bob, the comparision photos you provided have two different origins by their make up. The Mars photo in question have valleys carved into the surface while the other comparision photos are dried cracked surfaces or areas of ice melt "wedging". It Mars photo appears as one would see in strip mining techniques. Also there are two faint horizontal lines extending from top to bottom on the image. I'm not sure if this is on the surface of Mars or an image processing defect.
