Duck Bay, Victoria arrival point Options

[djellison]

Now yes - while it's fair to say we have arrived at the rim of Vic - the rule were that the 'arrival' date would be the sol at which the rover arrives at the point from which the mother-of-all-pans is taken... so we're not there yet. (i.e. We'll probably take photos when we arrive in Valencia on Sat PM - but personally, I wont feel I've arrived till the following morning when I have a look out the window....and you're right Fred - it's that FIRST big MOAP that is the important one )

But that doesn't mean we can't have a new thread

I LOooove these layers, they're everywhere. I feel like a little child in a new sandbox

Nico,

I'm not sure I agree with your layer interpretation, but put 10 geologists in the same sandbox and they'll come up with 10 different interpretations!

I think the layers follow the crater contours rather than bend up towards the edge. I think we can see some of the same layers that we saw at Endurance (I'm afraid I've forgotten the formation names), but it's difficult to make a confident correlation. I think the top is the evaporite, followed by the same aeolian layers that saw at Endurance. There then seems to be a bright conglomeratic layer, which may be the bright layer we can see on the far rim of VC. Below that are layers we haven't seen before, but because they are in shadow it's hard to interpret them from our current location.

I'd be interested in the views and comments of my fellow forum geologists.




Thanks for the base image Nico.

Castor,
I pretty much agree withthe boundaries that you've drawn. I'm intrigued by the layer you have labeled "Endurance Aeolian Unit". That layer is at the surface for a good bit of the cape. At the surface, it looks to me to have the appearance of the rocks that were calling "pavers" when we were at Endurance. Now we can see the near vertically eroded edge of these and it looks to me to be a large brecciated unit. The "pavers" are actually large angular boulders that have been planed off by surficial erosion and weathering.
If this is the case then it says something more about the timing of the erosion fo the crater walls. It has occurred since those large blocks were planed flat at the surface.

What do you think?
