The start of the passage.
The passage width varies but is about 1m on
average, the front section up to the two constricting stones seen in the
centre of the above photo is about 2m long. Past the constricting stones is a
further section of passage about 1m long
which continuously flares out to join the walls of the main chamber.
Note how the constriction stones do not reach up to the roofstones.
