THE BLEAK HALL DIG

(Based on Andy Legg's 1996 survey)

NOTES: The dig along Plaster Passage into the Railway Series was started in 1974 and work has continued intermittently ever since. The present digging session was started in the winter of 2003. The new passage in the Bleak Hall area is sketched in as a dotted guesstimate.

THE OLD WELLS ROAD DIG

(Based on Andy Legg's 1996 survey)

The dig at the end of the Old Wells Road is the preferred alternative site in wet weather, when the Bleak Hall dig floods.
