A bunch of new Navcam pan today.

Sol 3131 :


Sol 3131 :


And Sol 3135, with very interesting outcrops.


A color close-up :

It's Sandcherry Sol 3135:

The cross-eye is not for the faint-hearted though ...
Nice colors Ant

[Phil Stooke]

What a great place this is! Hopefully we have seen enough of the area for a good geological map of the outcrops to be compiled, and some serious analysis of the different units can begin.

[Stu]

Really intrigued by Sandcherry...

Ant103's sol 3135 pan in circular form - with a good view of the earlier tracks leading up to Kirkwood. The loop is nearly closed now.

Not surprizingly, after the bump of 3135 and the closing of the loop, we're set for some IDD work.

Lake Wanapitei on Sol 3135:


I recommend the cross-eye - the "golfball" really stands out there

[ronald]

And Timiskaming - same sol:

Here is my take on Lake Wanapitei (L257)

[ronald]

interesting Sol 3137 MI (rotated 90 deg counterclockwise):


This is made up of images from the mi_open_minloss5_DNTH2500_veryhigh series. At the data tracking website there is also mi_open_minloss5_DNTH2500_high and mi_open_minloss5_DNTH2500_medium. I compared veryhigh and high images and for me it looks more like stereo pairs or something - did anyone knows anything about this?

They also shoot a 7x1 pancam tosol - Matijevic Pan - this will be nice!

Sandcherry and Whitewater Lake look similar. Seemingly the rock is blue gray, fine clastic materiel with a yellowish weathering product. I would anticipate that if the yellow crust is brushed, underlying gray rock will be revealed as with Whitewater Lake. This apparent sedimentary feature seems to be associated with the extent of the spherule deposit and follow the contour – almost as if the spherule rich layer formed a sediment trap. Potentially clay cementing?

[ngunn]

Both Sandcherry and Whitewater Lake seem to have a shiny rind that weathers less and so remains 'bluish'. This suggests to me a surface fused by intense heat such as may have come from a bright bolide passing overhead. Every now and then the sand or mud would have been subjected to such events early in the early history of Mars.

[Stu]

Sharpened and generally messed about with to bring out textures...

[PDP8E]

Here is Sandcherry L257

[serpens]

ngunn, Since the brush of the yellow material on whitewater revealed underlying blue gray rock it would seem that the yellowish stuff is the weathering product and the raised blue gray surface is just more resistant. Differential erosion possibly due to variations in cementing or chemical variations in the sediment? This deposit is anomalous in that we have seen suevite and other impact breccia both above and below this level while this feature seems a very localised and fine sedimentary construct. This could tie in with the localised clay signature - source and eroded clay mixed in with surrounding sand. Could also of course be something else entirely. Were the results of the Whitewater APXS ever released?
