AndroclesB >>> with all this talk of Grabens,,, your mention of Malham Cove was I think prescient and also illustrative for how this thing looks to play out...
From Wikipedia:
A stream named Malham Beck originates on Malham Moor and emerges from a cave at the bottom of the cove. This is a different stream from the stream that flows out of Malham Tarn 1.5 mi (2.4 km) north of the cove. This latter stream goes underground at 'Water Sinks' about 1 mi (1.6 km) before the top of the cove and does not emerge until Aire Head, south of Malham.[1] The two streams were once thought to be one and the same, but experiments with dyes have shown that they are two separate waterways that go underground at different places. Their routes cross, without their waters mixing, behind the limestone cliff, re-emerging a few miles apart; indicating that there is a complex cave system behind the limestone cliff. Cave divers, entering the system through the cave at the base of the cove, have so far explored about 1 mi (1.6 km)

How about 7 or 8..?
You've gotta laugh.
