@65dBnoise my favourites for tosol are the navcam panoramas, maybe it's the horizon distortion but it's such a different feeling to see the height difference between the channel and the upper fan from this side... Once again, what a hundred meters do to one's perception 🤯

Dr. Robert Barnes with a summary of ongoing geoanalysis of the upper fan work by #PerseveranceRover , on the "Planetary Geomorphology Image of the Month" blog

"Stratigraphic views from the apex of the Jezero western fan"
https://planetarygeomorphology.wordpress.com/2024/05/31/stratigraphic-views-from-the-apex-of-the-jezero-western-fan/

#JezeroDeltaScience

Final paragraphs of the post: "The full synthesis of all the data from Gnaraloo Bay is ongoing, but the evidence so far implies that the stratigraphy at Gnaraloo Bay records the initial deposition of migrating dune scale bedforms eroding into Margin Unit deposits. This was followed by a stage of deposition of lower flow regime coarse to pebbly sandstone, probably in shallow flows which have been preserved where they were covered by the late episode of channelized high magnitude flood flow boulder deposition sourced from the Neretva Vallis inlet."

@65dBnoise I'm sure you've seen it, but for completeness: there's another bright one further to the left (https://mars.nasa.gov/mars2020/multimedia/raw-images/ZL0_1164_0770275017_909EBY_N0524312ZCAM03911_0340LMJ)

I see similarities too on that other one in @stim3on 's treatment (https://fosstodon.org/@stim3on/112519341200252355), only it's has more dusty faces. These clearly bright ones maybe have been "recently" displaced

This Memorial Day added an interesting twist to the daily grind of 🙂 Not only did it clear the rest of the rego-ripples it had to the north, but took advantage of the holiday to go on a picnic at a nice hill to the northeast 😀 🙃. Apparently the hill has a geological story to tell and the team's geologists are eager to hear it.

The path is a wild guess.

The maps were drawn with using data from 's and imagery by and

@65dBnoise your Ubuntu needs updating 😉

That was indeed interesting, because the hill(s) haven't looked much more than remnant scree, but there sure is comparative work to be done.

@65dBnoise you got a warning popup at the lower right corner of one of your maps

I wonder if it is possible to do a straight horizon pano of sol 1155, it's such a wide FoV...

The view towards the valley is wonderful from this spot, even in navcam resolution, AreoBrowser has a wider mosaic

's MastcamZ is ~1.9m above ground level. The tilt of the image may be indicative of (but is not equal to) the inclination of the ground where the rover was located when it captured the image.

Another ~25m and #Perseverance will be out of t̵h̵e̵ ̵w̵o̵o̵d̵s̵ the regolith ripple field and in the mostly flat part of the Neretva Vallis riverbed.

Tosol's ~17m drive brought the rover right where those ripples start. The dark area is where #Ingenuity will be hidden from our remote prying eyes.

@65dBnoise don't they usually take a navcam context after supercam? I'm guessing it's this one, so it sould be around the center somewhere...

Feels a bit random, I seem to remember similar small details before. I wonder what triggered the observation, can I borrow the tag you use to go back to things when the Notebook gets updated and see what they were looking at?

https://mars.nasa.gov/mars2020/multimedia/raw-images/NLF_1149_0768941495_989EBY_N0522540SCAM01149_00_0LLJ

@65dBnoise @tom30519 Yeah, that's the tag, now following it, thx!

Ok, so your context photo is from sol 1148. Still nothing out of the Mars ordinary (= extraordinary 😉 ), wonder why that specific rock. That sol had also SuperCam taking a telescopic view towards BrightAngel-like layers, nice!
