Amongst the "routine" sort of structural anomalies to be found in this image, some of them indicated by circles, there is the odd form within the medium-sized circle toward the center of the image clip.

It not only gives the appearance of being a v-shaped structure sticking straight in the air, but behind it seems to be the requisite shadow of exactly such a branched, upright structure... it almost gives a rather whimsical impression of a giant sundial, and might yet promise to be some similar part of a calendrical wheel of the sort of which Stonehenge is but one example. Such "Spacehenges" in fact appear to have been found on at least three extraterrestial bodies, including an impressive "Moonhenge" find by kksamurai.

Although such a circle does not immediately seem to be present, the form seems to be centered within some type of deliberate-looking geometric form, which may, in itself, be enclosed within a faint circle that will appear with subsequent enhancement.
