You've undoubtedly fulfilled your aims - the book is certainly inspirational. A book to savour and which will need several reads, given the vast amount of information in its pages.

Regarding the Trans Craven System, Brow Well, which appears to drain the valley south of Mossdale, would take the system south and eastwards. From Brow Well, it's limestone all the way to Greenhow via Trollers Gill.

BTW, has Brow Well ever been dived? The potential is enormous.

Thanks for that valuable extra information Graham - and a very good point about Brow Well.

There aren't any dives logged in CDG Newsletters for Brow Well (also known as Low Mill) but it was evidently investigated with diving gear, probably around 25 years ago. The last two Northern Sump Indexes give brief details, the upshot of which is that the water comes from a culvert on the north side of the main pool (which, reading between the lines, is probably impenetrable).

This entry in the index also gives some information on the hydrology, concluding that the water emerging is mainly autogenic (but with some dilution from active sinks).
This information is based on an article in Trans. CRG 1(4) [1950] pp 19-30, which I think was written by Jack Myers (so probably authoritative).

The index also flags up that the rising supplies the fish farm and that those who run this business aren't keen on cavers investigating (presumably because they're concerned about the water quality).

Out of interest, do you know if Brow Well is likely to be hydrologically associated with Fossil Pot? (Sorry to drift slightly off topic but this is actually relevant to the chapter Graham refers to.)

I read somewhere that the Brow Well water was discoloured when the mines were active but know nothing of Fossil Pot drainage.

Looking are the area as a whole (Langcliffe Pot to Brow Well), there are only three significant resurgences that I know of for an enormous area of limestone - Black Keld, Brow Well and one of the mine levels in Hebden Gill. There are other minor resurgences such as Davy Keld, Dib Scar and downstream of Ghaistrill's Strid. It seems to me that there's a lot of unaccounted-for water and that a Pwl-y-Cwm could exist somewhere in the Wharfe. It might be worth taking a walk up the Wharfe during the next big freeze to take water temperature samples.

There are three mine levels in Hebden Gill that have sizeable outflows - Duke's Level, Lanshaw Level, and Hebden Horse Level (in Hebden village).  Duke's Level drains the mines of Grassington Moor, Lanshaw Level used to be a mains water supply, and Hebden Horse Level almost certainly drains the area around Copper Gill. In addition, there is Thruskill Well which is used to supply water to a fish farm. This is adjacent to Hebden Horse Level, but is hydrologically independent.

There is also a large resurgence at Braith Gill, between Ghaistrill Strid and Grassington Bridge, which Leakey considered as a candidate resurgence for Mossdale during his initial investigations.

That's very interesting; thanks both.

Just to amplify on your point Graham (about the pollution in the 60s at Brow Well) the CDG Northern Sump Index gives a reference source for information about that:

Northern Cavern and Mine Research Society Memoirs, 1965, page 1.

For anyone interested, the NMRS now has these early NCMRS Memoirs online!

(With thanks to Phil Murphy for pointing this out to me.  :) )

Thank you to John Cordingley, Dave Haigh and the publishing team at Wild Places.... An absolutely superb book, the best caving book for a long long time..
Detailing the joys of cave discovery and certainly feeding inspiration to take up cave exploration...
Thank you again for providing us with such a great book....  All your hard work is certainly appreciated !!
I would expect demand to outstrip supply........

If you haven't bought a copy of this yet then I strongly recommend you do before they all go!  Picked up my copy at the weekend and haven't put it down yet! Massive congratulations to Dave and John on a classic piece of Caving literature! And money for a good cause too, win win!!
For me the kingsdale section stands out as an insight into the mind of cave divers which is second to none, and the stories surrounding Gaping Gill are excellent. Don't assume you've heard all the stories about these classic caves because there are some great anecdotes in here! Great effort both  :clap2:

I have 2 problems with this book
(1) you can't put it down
(2) it should come with marriage guidance advice because my(non-caving)wife complains I'm not showing her enough attention because of complaint (1).
Brilliantly written book 📚  that I have read and re-read which has caused complaint (2)  :thumbsup: :thumbsup:
