Sol 1496, October 21, 2016. Curiosity did its full drill on the target named Sebina, as seen in the cropped Navcam frame above and in the MAHLI shot at right. Note the nodules shown in the MAHLI frame. (Both images enlarge when clicked.)
As noted, winds are active here. The drill tailings blew off to the right of the hole. And in the Navcam frame, dark sand between the rock slabs shows ripples indicating winds are moving loose material at surface level.
