At this point I felt tempted to dig a deep hole and see if I came upon further bone fragments or other remains. I didn't do so because I didn't have the required permission, but I think this is definitely what should be done, in the context of current endeavors by the Sobibor Archaeological Project and its competitors at University of Hartford to document this Nazi extermination camp and fight Holocaust denial by archaeological means.
For what can be a more effective means to fight "Revisionism" than bringing the contents of the mass graves to the surface, having the human cremation remains analyzed by a forensic expert to certify that they are human remains, quantifying them as precisely as possible, and thoroughly documenting with reports, photographs and video clips every step of the process, ever single core sample, every layer of human ashes and every human bone, bone fragment and tooth that is found?
And what can be less effective in this context than an archaeological reconstruction of the Sobibor extermination camp that does not include a detailed and thorough investigation and documentation of the contents of the Sobibor mass graves?
As I already said in my previous update, the former would be a deadly blow to "Revisionism". The latter, on the other hand, would be much hard work not worth the effort.
