On Sol 690, Oppy PanCam captured some beautiful images of the rocks, with radent afternoon illumination giving strong relief to stratifications and 3D structure.
Here a stitch:
I already asked to Malgar to make a photoclinometry on this...

Festoon bedding can be confidently observed in plan view, imho. The "T" geometry Emily pointed out is, I think, quite diagnostic. But in this case, we can see the "T", and several pretty stupendous examples of nested bedding in ripple troughs. There must be an "official" name for that geometry, but I'll be damned if I can remember it. I've always thought of them as "eye" structures, because the nested beds form elliptical, or eye-shaped patterns when sliced this way.
I agree that all kinds of shapes can be created by differential weathering/erosion in rocks with layers, but it really doesn't appear to me that these particular layers are horizontal/flat. I really thought the fortuitous discovery of this special slice through the bedrock was pretty convincing. -------------------- ...Tom

On sol 705 Opportunity took a series of L6 "super res" images of various rocks showing fine layering details; I stacked them, resampled them by a factor of 1.5 and then sharpened them a little using an unsharp mask.
