I think it's time for a new topic. We are effectively at the entrance to Gediz Vallis now that we have climbed this last slope on sol 3871.
The previous topic described the Greenheugh Pediment. We made a valiant attempt (two valiant attempts really) to explore its surface. It was too rough for Curiosity's dainty wheels but its outer edge was examined in detail. But now there are new targets: a crater cluster, the Gediz Vallis Ridge whose upper part is accessible from this level, and the large valley and its central sinuous valley as well. I attached a picture seen at LPSC - I am embarrassed to say that I can't remember where it was from. Usually I have detailed notes of sources but this one slipped through. Maybe someone will recognize it and I can add a source. It gives the name of the butte at the western entrance to the valley, annotated onto the JPL map. Phil

Indeed quite the vista unfolding as Phil described. Here's a sequence of drives that topped the ridge by going through the area of the double alcove, using official mosaics between Sols 3860 and 3873.
Longer steppable drive animation with a combination of official and Jan's mosaics from Sol 3435 to the present. -------------------- Steve [ my home page and planetary maps page ]

Been a while since we saw a wheel check (due to difficult terrain)
This is 1 of 20 wheel inspection MAHLI's acquired on Sol 3878.

This is the worst of the images, but a frightening amount of damage to the most damaged wheel. No wonder the rover planners have worked to avoid crossing any terrain with pointy rock surfaces. With three adjacent grouser bars Brocken or missing in the image, I wonder how close to failure this wheel is and how much more damage it can accumulate and still keep on trucking

Thanks Fred. I must have missed the 3492 image. It is reassuring that it is basically unchanged over that length of time.

QUOTE (fredk @ Jul 6 2023, 10:42 PM) That damage has been pretty much unchanged in hundreds of sols... Here they are side-by-side (cropped and sharpened) The changes to the rover's driving algorithm has really kept this rover trucking...

Latest drive back more to the southwest using official mosaics for Sols 3873 and 3880.
