Piccadilly Pot, St Arvans
A series of shafts descends via very short levels or deviations to about 20m,
where a rift goes north through loose territory for 8m, and south of the current dig face for 15m,
also descending another 3m, plus a 6m side tube to some calcite.
Digging is on Wednesday evenings, finishing at 10pm to allow a swift drink in the Piercefield Arms.
