interesting Martian photo
This one is of interesting Martian dunes. If you look at the bottom of the photo and about 1/4 from the top you can see amazing detail in them. Many have hatchings on the sides perpendicular to the direction of the dunes. It might seem ordinary but this is an unusual photo.
