"Roberto:
You have been challenged to actually show us a verifiable excavations and the huge amount of human remains that you allege.
Your recent posting of various 'walls of text' which do not address those challenges are simply dodges and below the standards of this forum.
However, I have left the photos that you do think prove your claims about Ponar.
Cheers, M1"]
We now get to what are probably the most interesting images in the Yad Vashem collection of photos captioned as having been taken at Ponary.

There are two photos in the Yad Vashem archives showing scenes similar to those described by Pflüger, Hamann and Schroff, but apparently taken by someone other than Schroff (though one is captioned as being from Schroff), as Schroff only mentioned two photos in his testimony.

At this site, near the city of Vilna, the Soviet authorities prepared huge pits for storing petrol tanks they still had not filled.

It would be interesting to know more about who took these photographs and when they were taken.
