Hello Robin,Interesting area around Ribblehead. All in Great Scar limestone, but is there nothing major, or deep rather, because of lack of deep valleys in the vicinity? Or some other control? Just pontificating from my armchair.
Without wanting to stray off topic - worth looking at the chapter which covers this in the Waltham & Lowe Caves & Karst o t YD book. But - look at the O.S. map and you'll find Goat Close is in the bottom of Ribblesdale. I think there's something about this in the most recent CDG Northern Sump Index but bit busy to check for you. If you really want to know PM me and I'll (eventually) sort a bit more detail for you.
