latest forward hazcam Images from Rover website suggest its moved a little further south along the crater wall:

Pancam images from exploratorium, I don't recognise this rock:

Could it be the rock visible in the forward hazcam image but with pancam and the rover looking back at it from a point further forward than in the hazcam image?
There are some VERY fine layers visble in it.
