There's a UFO site which claims that the below image is captured by the Mars Global Surveyor and is
of what looks like pine or other similar type of trees. I think this image is important because the trees seem to be on a hillside, and for the first time tree trunks can be seen from this perspective rather that just an overhead view which makes the trees easier to identify as life on Mars. They look like a rugged type of tree you might find at higher altitudes and in tough environments.
Is there any evidence that this is a genuine image taken by the Mars Global Surveyor, and is there an official explanation from NASA or any other space agencies? I would expect that these images, if real, are of a specific type of rock formation.
