The chamber entrance from above (SE is up).
The chamber here is very narrow, only about 0.5m wide, because of its off-centre
placement in the cairn
it meets the kerb at an angle. There is a low flat stone set between the first
chamber side slabs, this looked
very much like a sill-stone. A more substantial stone stands between the kerbs
of the entrance, this may be
a symbolic "blocking" stone.
