Hi Chris,
Had a look at the original plan I made, now this is my interpretation of what we see in the mine. The area you are looking at is behind the plastered area, on the LHS going inbye.if you look in this area there is a cross cut going across which eventually reaches a parallel flat to the main one. It is 'hard travelling', since much of the cross cut and flat are back filled..
The sump from the air drift is above Smallcleugh coming from an air drift which starts at the main level and is we'll run in.
It came across past the rise up to New Fan flat and over towards the main flat.
A dotted line signifies passages that were known to exist when the survey was being made but were not accessible to him.
If you wanted to get into this air drift you would have to put up a large maypole in the rise to New Fan flat, since the entrance shaft goes above the flat into the old air drift.
This is why this area is always wet! Water comes down from the air drift, not from the New Fan flat.
I am not sure if Varty's cross cut is the one behind the plaster,
Or one from this ventilation cross cut.
Remember until Rampgil was driven up under Smallcleugh, some time around 1830's ventilation was a major problem, hence the ventilation door and plastered walls.
