small off-center clump of twisted-up bristles sol1931 and the side view, so wow that circular groove sol1933 really is correspondingly tiny, i'm always overestimating the size of these images, the circle is not several cm, but mm across. i was interpreting the twisted clump to be caused by the brush hitting up against the lip next to the circle but it seems to have been there sols earlier.

...i'm always overestimating the size of these images, the circle is not several cm, but mm across. Good call... Using Gerald's MAHLI ruler on the pre-merged image from sol 1931 with a focus count of 13979 shows the groove diameter to be just 3mm. If I had checked that first I would probably have not called it a sandy deposit from the APXS |
