Area position

A small hole that leads to a 25m deep shaft to a floor 4 x 3m. A low passage at the base chokes after 2m.

In October 2013, the site was described as a triangular shaped opening approx 0.5m diameter, approx 10m above track with an old spit at the entrance. About 3m to the west is a further entrance covered with rocks, also a rift above the main entrance, these both join the shaft close to surface.
The choked alcove at the bottom appears to draught in and may be worth digging.
