Here's the survey referred to above marked up:
I?ve had a look at the survey, and the ?new? passage is not on it, so I?ve marked its rough position in red, with the pitch marked.
Other features of interest on survey are:
There appears to be a passage going over the top of Dome Pot; in fact, I think that this is the passage at the bottom of Dome, the N branch going to Shale Cavern and the S branch to the ?Zig Zag? (as it is marked on the map). This is shown as ending at ?FK.? (which I?ve marked as point Y). Actually, this goes through to the wet way, entering the passage at the foot of the 100 ft pitch ? Piscina, is it? The way through is very narrow; I had a look at this last night, but wimped out. The passage is far too narrow at floor level, the only way through is at a much higher level in a tall, narrow rift, but the climb up to it is very exposed, and I didn?t fancy falling 20-odd feet. I have been through it before, and I remember looking out over the streamway at the other end. There is an obvious chockstone at the top of the climb on the Dome side, so maybe last time I was there there was a rope hanging down off this chock ? can?t remember.
Tell you what, though, a trip to the bottom of Lost Johns? down the wet way, through this passage to Dome Pot, and through the connection to the Centipede route (Dome Junction) would add a whole new . . .
je ne sais quoi . . . to the place; getting tackle for Shistol, Candle the Battleaxe and the last pitch through that tight passage would be a bugger.
Another feature of interest is the point marked ?(FF).? (that I?ve marked as X). This is the end of the chamber below the pulpit pitch, and degenerates into a low crawl. When I looked at this I couldn?t be bothered going through it because (a) I couldn?t be arsed to take my SRT kit off and (b) for some reason I thought that it was heading for the Centipede route; I?d got it into my head that the passage to Centipede follows roughly the same trend as does that to Pulpit, so I figured that they must be fairly close; also, if you look around when descending the Centipede, you can see lots of little holes leading off. Well, obviously I was wrong, and this passage is heading into a ?blank? area (as, indeed, is the ?new? pit).
