I doubt any glacial influence Bill if that is the possibility you imply. To the west Neretva Vallis is a typical high potential energy river valley, deep incision with steep sides. But in the lower reaches the river seems to have widened, spreading its energy. Change in lithology perhaps? The erosional environment at the crater would have been variable and complex. Initial penetration would probably have been groundwater tunnelling and the river would have banked up and spread. There is clear evidence of occasional high energy deposition at the delta and variations in water level with maximum prior to the eastern outflow. This, combined with the susceptibility of Jezero's ejecta blanket to erosion may be the explanation for the channel configuration.

[Bill Harris]

I was suggesting a Glacial hmmmm?? . But not strenuously. I tend to pigeon-hole V-shsped and U-shaped valleys as a matter of habit.
That next sentence should have read "subsequent aeolian erosion" ; the 'appliance...' was an autocorrect funny.
Onward!

SHERLOC appears to be having issues with a stuck cover. A number of diagnostic activities appear to have been performed.
Here's a great animation showing a rotation of the turret.

Here's a look at Sol 1042 afternoon imagery following the drive that Sol along with a large version link. Thanks to Paul for image and camera navigation info and Kevin Gill for the raw image utilities that all help prep the images for my processing.

Here's a look at a mosaic from after the Sol 1045 drive along with a large version link. Thanks to Paul for image and camera navigation info and Kevin Gill for the raw image utilities that all help prep the images for my processing.



And also Sol 1046 with a large version link.

Nearing the South bank of an ancient riverbed, and hopefully an upcoming MastCam peek at Ingenuity, and what happened down there.
