Note the coarse, conglomeratic, truncated unit below.

Adding onto Bill's observation, I think I see a fining-upward unit below the truncation, and a fining-upward succession with large-scale cross-stratification that has flattening-upward bedding.

My interpretation of these observations, in the context of the position of the outcrop, distal to the more proximal part of the delta, would be that these are the deposits of supercritical bedforms, likely cyclic steps (the lower coarse unit) and long wavelength antidunes in the distal delta front and toe-of-clinothem lobe element and feeder channel to lobe element transition zone.

Tim, this is a wonderfully dynamic area.

1. Sol 572 Front Left Hazard Avoidance Camera A.
The small sand dune under the turret at the end of the rover's robotic arm seems to be of particular interest.
2. Mastcam-Z image with stretched colors and scale.
3. SHERLOC WATSON camera image with enhanced colors.
The size of the rounded grains is roughly 1 mm.
The location of this image is most likely somewhere in the right halfth of the Mastcam-Z image.



Further investigation of this dune is underway on sol 575 with PIXL.

_ The diameter of most of the dark grains is about 50 µm.
_ The dark grains show moving light reflections. In some cases they alternate between completely dark and an overexposed reflection.
_ That is, the dark grains have a shiny surface, some probably even have shiny facets.
