Northern chamber passage.
This is the end of the passage through the long cairn material, the orthostat
left centre shot is one of a pair of portal stones let into the round
cairn which contains the northern chamber. The portal stones are set parallel to
each other but at an angle of around 40 degrees to the sidewalls,
the northern portal is out of shot behind the masonry on the right edge of the
opening.
The passage floor in this area is uneven due to the presence of two large
irregular blocks which can be seen above.
