re: What's your take on the rock at the center bottom.of the image...seems to have no layers and no berries...
I think we are looking down on the top layer of the rock. I saw some rocks like this in Eagle Crater. I think I might see some berries, but I can not be sure.
It is possible that some rocks around Endurance are not from this region of Mars, and have been thrown here by impactors- like Bounce.
A closer look would tell us more.
Good eye to spot that.
