What was happening around the second dig in Oct. 1991? Because it was the second dig that they brought in the bulldozer and then sifted through every inch of the tons of soil to find the rest of the bones.
I don't have the right books with me to produce the answer for this myself, sorry.

If you want to know my honest opinion, the climate around the so-called second dig in Oct. 1991 was INCOMPETENCE. And it's never helpful in Russian history to underestimate the overall incompetence of the government, or shall we say here, officialdom. "In this country we can't even hang people properly," as one Russian intellectual complained in the nineteenth century about the bungled hangings of certain Russian revolutionaries. These executions went all wrong, and the people being executed had to bear being "executed," then resurrected, and executed all over again,
twice, simply because the Russian executioner in charge didn't know how to tie a noose properly. Can you imagine dropping through the scaffold on a noose, which begins to strangle you, enough to cause you extreme discomfort but not enough to kill you - and then you're suddenly being dragged up to the scaffold again, only in order to be dropped through it a second time - and ohmygod, once again the noose doesn't work? You're strangling, but not dying... how does that feel? Only the third time did the executioner finally manage to get the noose right. The prisoner was finally killed. But only after undergoing unimaginable mental, emotional and physical tortures - not because of some "conspiracy," but simply because the Russian authorities didn't know what they were doing.
So AGRBear, IMHO you keep looking for conspiracies where there is only incompetence. Yurovsky screwed up. The Russian authorities in July 1991 screwed up again (hey, big surprise), and, if we're to believe other reports, screwed up yet again in October of that year, in bulldozing the site of the mass grave in Pig's Meadow. Bit personally, I would have been surprised if the Russian officials had done anything differently. It's not in the tradition of Russian officialdom to be competent and thorough. If you doubt my word, just read Gogol's great novel,
Dead Souls, or his play,
The Inspector General . Then you'll see that official incompetence is part and parcel of Russian culture. Just my two cents.
