R-MastCam 4 frame mosaic from 1638 that features the small outcrop where the rover crushed the small dark rock: Post Link
The mosaic shows us a number of small dark pebbles / rocks on top of the outcrop.
Possibly the same material? Image quality was reduced to meet the attachment limits.

Thanks, Jan - and here is your panorama in circular form. Quite a messy patchwork of sand and rock.

I haven't posted anything for a while, so here is the sol 1643 Lpancam view:

nice! and here's my eyestrain-inducing attempt at a wide baseline anaglyph of a small compatible portion of those sol1642 and sol1643 views.
i suppose the downlink of part1 of the 28x1 mosaic offset of Vera Rubin Ridge is on backburner, just thumbs for now.. i'd thought sol1642/1643 was to be the offset pair but i must be wrong about that..

USGS Mission Update for Sol 1645 Link by Michael Battalio (ENV Science Theme Lead) and Ken Herkenhoff (SOWG Chair)
QUOTE
The APXS will still be deployed on The Hop early on Sol 1645, and to avoid using battery power to heat up the arm, we'll wait until early afternoon to move it out of the way. So we had to pick ChemCam and Right Mastcam targets that would not be obscured by the arm: A bright vein named "Snows Point" and a knobby-looking rock dubbed "Clam Ledge." Navcam will then search for clouds and dust devils before the APXS is retracted from The Hop and more drill diagnostic tests performed. The Navcam surveys are part of an ongoing Environmental Science Theme Group (ENV) campaign to meticulously search for dust devil activity in Gale Crater. It is important to maintain a regular cadence, because as the location of the rover and thus surface topography changes, the size and number of dust devils can change. In concert with the imaging, simultaneous REMS measurements can detect pressure drops if vortices travel over or near the rover. This set of observations is needed to constrain model simulations and is an excellent example of two different instruments working together to improve our understanding of the meteorology of Gale Crater and dust lifting processes on Mars as MSL traverses up Mount Sharp. ENV also plans to repeat the Mastcam optical depth measurement and Navcam cloud movies that will be taken early in the morning of Sol 1645, to check for diurnal variability. A Mastcam afternoon sky survey is also planned, to characterize dust in the atmosphere. Today's drive will be followed by the post-drive imaging needed to plan contact science and another drive this weekend.

1645 post drive partial pan L-NavCam. Midnight Plants reports it as : 20.7m ENE (63º) Link
MS ICE so not pretty... But it may help fix the location until the remainder of the images are available

A very interesting USGS Mission Update: Sol 1646: Traction Control Driving
QUOTE
MSL drove a little over 20 meters on Sol 1645, toward the big sand dune to the east that is the subject of a science campaign that will hopefully start next week. Another drive toward the east is planned for Sol 1646, with post-drive imaging to set up for contact science. The drive will include the first use on Mars of traction control software that's been tested and fine-tuned in JPL's Mars Yard since last April. This new software allows the rover to drive "softer," meaning that when the rover detects that a wheel is driving over a rock, it slows the other five wheels to avoid pushing the wheel into the rock while the wheel climbs over the rock. Curiosity's first use of traction control has been planned for months to begin about now and is intended to validate the new software for optional use in future drives.

Before the Sol 1646 drive, ChemCam will observe targets "Bald Rock Ledge" and "Porcupine Dry Ledge" on one of the layered outcrops to the right of the rover. Then Right Mastcam will acquire mosaics of both of the layered outcrops shown in the picture above. After the drive, Navcam will again search for dust devils and ChemCam will observe a target selected by AEGIS. Finally, Navcam will search for clouds and SAM will perform an engineering baseline test.
