Re: interesting Martian photos
As i posted below these features are above ground, not below according to the shadows on the dunes. This also seems to make it unlikely they are dunes as the smaller dunes in the area are pretty normal in shape. This is another feature that may be related, but it is not polar. Photo m0302048.
