OPPY took this color image near sunset on 3017 (July 20th?) It just got down yesterday? SOL 3017 would put it near Sao Gabriel, just before the hop over to Whim. I see a 'gysum' like rock in the masthead shadow? Click to view attachment
Interesting vein of seemingly more erosion resistant material running through the slabs just above the RAT in Walfly's last post (#508).

Would it be a reasonable assumption that this vein postdated the impact that produced Endeavour?

I don't know if there's been a consensus on this yet, but if these layered rocks are part of the sulphate Meridiani layers set down after the impact then your assumption would be correct because the layered rocks themselves would postdate the impact.
Experimenting with panoramas. There are some great new sets that Oppy sent down recently. Since none of the pano-meisters have posted yet, here's a quick nav-cam pano from sol 3036. So cool to be in the creek!

Or standing in the middle of the street. I want to look over my shoulder for the bulldozer that carved this thing. The latest processes shaping it appear to post-date the original layering in the trench, development of the light-toned upper surface to either side, and formation of the rough terrain surrounding Cape York. Fascinating.

Awesome pan, walfy! I'm assuming this feature is an expansion-related dip-slip fault?

Lots of nice new rock shots coming down. Here's one in particular:
That's a beauty!!! I NEVER get tired of the odd ways these sulfate-rich rocks erode!

Looks like there may be a drive sol planned for sol 3040... Now the race for the clays is really on!

Opened a new thread to cover the trek by the east side. New pictures and discussion should be done there but everything related to Whim Creek should still be posted here.

It's not too late, I think.
Sol 3020 panorama, I really love the light angle.
@James : excellent work, as usual

Did Oppy break the rock in the background ? If so they must be dry and brittle.
