I'm looking at a lot of images for my polar wander theory. These would all be on the edge of a former pole at Meridiani. There are a lot that look like there were water and ice flows heading north.

The long ridge is unusual.

Some more examples in the crater

In the center of the image there is an apparent mesa, and the ridges divide it into several parts like a dinner tray.

Right at the bottom of the image is a very unusual crater. It connects to an apparent channel that appears to have carried a lot of fluid. Presumably the fluid came from inside the crater, but this would imply a huge amount of subsurface water was released. It may be the channel coninues on the other side of the crater though.

Similar ridges in the area but much smaller.

More of the ridges.

This is a little further west. If you look towards the bottom of the image there is a pass between two higher areas of land, with a small long and narrow rock in between the two. Looking at this rock, there appears to be a trail heading upwards. It looks to me like this is debris captured behind the rock from a water flow, and further up the dunes are like ripples from a water flow.
