I was looking over some photo in the MSSS or Malin Space Science Systems archive and found this interesting tunnel. These kinds of tunnels have been found in higher detail than this, but this one seems to have a tiny branch the moves off. Many believe these are transportation tunnels and they very well might be. Living under the surface of Mars seems to be easier than living on its surface. There also looks to be some tall long structures in the inside of a crater. This crater is located at the far upper right of the original photo. The Tunnel is located at the lower quarter center of the photo. SCW
