Only the Illusion Pot end is on the Survex model I have, but it looks to be pretty consistent at 265m asl.

Thanks George - so it's lower. Mind you, that's not necessarily a killer for the west to east (or vice versa) passage idea. Phreatic conduits do swap inception horizons and change levels. A few obvious examples are:
* the steep descent from the downstream KMC sump to the upstream end of Keld Head.
* the steep ascent of the East Kingsdale Branch of the KMC up to the main KMC level.
* The steep ascent from North Craven Passage to South Craven Passage in Car Pot.
* The steep descent of The Ramp to the much deeper Metro in the dowbnstream Lancaster sump.
* etc . . . .
Just in case anyone wants to accuse me of "pontificating", these are facts. I've been in every one of them, frequently. And surveyed three of them, so I have the data to prove it.

Thanks for that Pitlamp. For those that are interested, a lot of the survey data for the 3 counties area is accessible on the Cave Data Registry here: http://cave-registry.org.uk/svn/NorthernEngland/ThreeCountiesArea/survexdata/
(see the threecounties.3d file for everything)
What I did notice whilst spinning things around was that Dale Barn 3 (the Expressway) is at exactly the same elevation as the upstream KMC and the Milky Way. Obviously it doesn’t mean they’re connected, but it’s definitely noteworthy.
