Lee: Another explanation for this strata just occurred to me. If you look at the wider MRO context camera image (available here), it is clear that this feature is at the crater’s central peak, though that central peak appears to have been worn away.

Maybe we are seeing the base of that peak, the rest long gone because of wind and maybe even ice erosion. The vertical twisted strata we see would make sense for the central peak of an impact crater.

I keep looking at the cliffs on the lower left of the full image, and then at the 90°inverted strata so close by…. And at so lower depth…. What the heck could cause such a massive distortion without destroying the strata? The distortions seem to have circular patterns, so probs crater related… But how? My only thought is perhaps relating to an ice and rock mix in the bedrock being more flexible than just pure rock? I can look at a sedimentary rock layer on earth and have a decent guess how it ended up that way…. Looking at this just makes me confused!!
