MSSS claims that imaging the north pole of Mars is very difficult because the spacecraft's orbit, and the seasonal clouds over the region, provide very narrow windows of opportunity.

There are several other images of this area. Unfortunately, most are riddled with data errors and are taken from an obscure angles. Of the handful of usable examples showing these features, MGS MOC image M07-01290 may be the most useful. In this image one can clearly ascertain that these features are rectilinear and arranged in what seems to be a non-random pattern.

 
This is a crop from the center of the image.

This is a crop with a slight enlarge and modest levels adjust.

This viewpoint is exaggerated when the image is inverted.

More analysis of this image is forth comimg, but please see the next link, more monoliths for other image examples of this enigmatic region.
