A speck of dust sits on a pedestal - this is a smallish piece of dust, only about 1/100 the thickness of an average human hair.  The dust made its own pedestal by protecting a small area from the high-energy plasma that I was using to etch away the surface all around it.  Apart from the dust (and from that rough area in the background), the surface came out reasonably smooth.  I gave this sample an extra clean and zapped it with plasma again - afterwards, all these weird features were gone.
