What about Treblinka? Was it the end of the line or was it the end of the line?
Treblinka was the end of the line for transports taken there, just like Belzec and Sobibor, but like at Belzec there is the concrete of a huge memorial covering most of the former mass graves area at Treblinka, which would have to be removed first.
At Sobibor, on the other hand, the "ash mountain" memorial covers only a relatively small part of the area where the mass graves are located, and only a part of two of the seven mass graves in that area are under the memorial, as you can see below on a map by Prof. Kola and a satellite photograph section, both with my numbering of the graves according to Prof. Kola's description thereof.
So an archaeological investigation of the mass graves at Sobibor is comparatively easy. All it takes is the will, the expertise, the equipment (core drilling devices, shovels, maybe excavation machines for the deeper layers) and the required government permission to do so. The people of the Sobibor Archaeological Project are willing to do this work, they have the expertise and can obtain the necessary equipment. The problem is obtaining the permission, as the Polish government does not easily grant permissions to do archaeological work that involves disturbance of Polish memorial ground.
