Kris,
It depends on preservation, but a disinterred cemetary shouldn't have wood
and bone fragments in your test pits. I know that sounds obvious, but if
you have a good bulldozer operator who can scrape the ground in thin 1/4
inch layers you'll see outlines of the grave shafts or pull up bits on
coffin hardware and coffin wood if the graves haven't been moved. If they
have, you'll probably find very indistinct grave edges. I dealt with a
supposedly disinterred cemetary (it definitely wasn't) where all the
headstones had been removed, but the graves were still there underneath the
plow zone.
