High view of chamber remains.
We are looking down on the cairn centre from the north here. The large stone and
its partially buried neighbour in the centre foreground are
slightly displaced remains of the western chamber wall. The four stones flush
with the surface, arrowed red, are intact stones of the eastern wall.
Using these references, some idea of the original central chamber floor space
can be obtained. The tilted ultra-wide lens used to capture this
has caused distortion of the circular form of the chamber.
Note the surviving erect circle stone, just the the left of the True South
ranging pole.
