Excavation could provide evidence for the movement or non movement of stones . The cairn is likely to have followed the erection of the structural stones and their sockets would be self explanatory . There is also the possibility of a revetment and any disturbance to that would also provide info of possible movement of stones but the sockets would be the most informative .

Do you mean a cairn or mound covering the tomb or just the cairn type material around the base George? There are no sockets below ground level other than the closure stone. It is possible that the cairn material to the base was only provided once the structural problem occured and after the stones were switched.

The material that is left around the base which would have been more substantial . Nearly all portal tombs have a surrounding cairn so it's likely that the one at Trethevy would have been part of the original build .Without excavation we don't know what is under the material ,there could be a revetment and there could be sockets as load bearing stones are not likely to have been just inserted into the cairn material .
