I think this has to be about the most interesting picture I've seen yet. The only thing the pattern reminds me of is the cracking pattern you see in mud that has dried, but that kind of pattern is not that rectilinear - very strange stuff.

It's even stranger if you carefully follow each ridge though it takes some time. At each point ask yourself how geology would explain it. When the ridges climb hills, go through valleys and even over the top of hill. When ridges disappear then are found to line up perfectly with others further along.
Also some follow in the same directions as the layers and others are at all different angles to the layers. It's as if the geology in the area has no control on the shapes of the ridges.

Where would this area have been prior to the last change in axis tilt by Mars? Near the equator?

Greg,

I would be very interested to know if there is any data as to the nominal height of these walls. IF they are about 8 feet thick as suggested by AB then (assuming they are artificial) what function could they have. My thoughts would be water reservoirs; which may have become necessary toward the end of any habitation period.

I think the height of such walls and the vertical or uniform slope of such walls would be the strongest indicator of natural vs artificial.

Are there any current speculation regarding a natural process that could have formed them?

The local solar time in this image E1201527 is 2200 which is just short of midnight. That's still sunny because it's summer on the pole. Nothing seems to be throwing much of a shadow in any direction. That implies to me the sun is not far off overhead here. The shadows seem to be about a pixel wide so that might well translate into walls even 3 to 5 pixels high. That would seem in proportion to a constructed wall, higher than it is wide.
There aren't many geological processes that can form this kind of pattern. The usual one is cracking, but these seem too regular compared to the normal cracks, besides cracks go into the ground not above it. Sometimes ice cracks and the weight forms depressions in the ground in the center of the ice but those are usually rounded in the center, which is not the case here.
Sometimes you get faults which have a similar shape though usually not sticking out like this, though they are known to be irregular. Rock can crack in right angles but it begs the question that if this is a known geological process then why isn't it found all over Mars? This is virtually the only place on the planet with this kind of formation.

Here are some examples of polygons which seem quite different. Even this one is odd though:

I guess you could corral those Martian bison in this photo as well. Even some handy entrances to hang the gate.
