Not that I buy the conspiracy claims, but I did notice something rather odd in one of the photos. (Warning link to huge pic coming!) If you look at this photo, you can see where the images aren't correctly stitched together. (To find it, scroll down to the bottom of the pic, then scroll over to the left, and you'll see two spots where there's rocks which are cut off because of the stitching.)

What I find amazing, though, is that at the top left portion of the image, just above what I assume is a dry riverbed, is what looks, for all the world, like a turtle.
