Where have you been seeing hints towards dessication patterns, Paul? I see hints towards layering of sediments of variable cementation, fracture fill, possibly syneresis cracking of a soft and fresh sediment. But I've difficulties to find hexagonal or rectangular shringkage patterns more typical for dessication, unless it's been heavily distorted by a subsequent process.

Gerald, thank you (as always) for your expert feedback. The 'hints' I referred to are those dust covered features of the lower portion of this frame.

Thanks, Paul! These escaped my notice. There is indeed a considerable similarily with dessication patterns. Thanks again for pointing to the according image!

...dessication patterns....

Thanks Gerald, here is the processed / cropped mosaic featuring that outcrop (4xR-MastCams), scale bar from AlgorimancerPG.

Weekend workspace, Sol 1802, 6 x L-MastCam (MS ICE) raw colours, sadly no mission update for the holiday weekend, so no target names

Neat to see the lighter colored rocks on top of the ridge.

That lightness could have more to do with the angles of reflection than composition of the rock.

No - the Hematite ridge really is a brighter tone of rock - it's clearly visible in HiRISE and CTX as well as from the surface.

Mosaic using just 8 L-MastCam frames of what will eventually be a much larger mosaic. These raw Sol 1805 frames were assembled in MS ICE without additional processing.

After a ~66 minute drive on Sol 1807 Curiosity arrives at site 65/3200: L-NavCam partial pan, roughly assembled with MS ICE may help fix the location.

This is Jan's sol 1800 panorama in circular form. I also made a circular projection of Paul's partial panorama from sol 1807 to get a good location for the route map.

A great image, Jan - thanks. Here is a circular version showing how we are perched on the edge of the ridge. The atmosphere is getting clearer, so we see the crater rim quite well. Soon we'll have the widest view ever of that distant landscape.
