Finally got the arm deployed. Hope they get done with this in a day or so and get on the road again.

That image is from yestersol. Oppy has moved a few dozen centimetres forwards after that:

I fear it's still not close enough to stick the IDD on the walls of the trench.

Can someone explain this strange feature imaged by MI on Sol510? (context Hazframe on the left):

My best guess is the "slab" with blueberries sticking out of it's end is a "divot" of compressed soil released from the tread on a rover's wheel. It's extremely soft and barely cohesive, and is being sandblasted by saltating fine sand grains, eroding it from the end and also stripping away some sand from the lower surface at lower left. Blueberries shield the soft compressed fines from the sand and retard its erosion where they protect it from full-speed saltating grains.

A berry laden clod dropped off a whele, which has since been wind erroded a little?

Yes, seems the most plausible explaination...
