The GPS reading was taken at the top edge of the "shaft".
A cave cut into the hillside so that the top edge is a 5m drop and the bottom side can be walked down (through brambles). At the bottom, a small stream comes from a sumped pool and flows into the field. It may be possible to drain the sump to some degree and it is probably worth a dive.Holes above the sump all choke.
