Pitches in Yorkshire that exceed 50m

[Fulk]

Plus I think 110m is an overestimate anyway OR possibly a measurement from the lowest point of the entrance doline rim; I think the shaft is supposed to be 98m. I've not done Dihedral but on that basis I'd assume that is also less than 104m.

I once did the 'Jib Tunnel / Dihedral Route' but instead of using the rebelays and deviations, I rigged from the bolts in the roof of Jib Tunnel to get a free hang to the floor of the Main Chamber. It was a warm, sunny day in a spell of dry weather, but even so it was pretty wet for much of the way . . . not something to do right now! Unfortunately I can't remember how far it was.

I was involved in measuring the depth of Lateral Shaft direct, from the Jib Tunnel jumping off point; it was exactly 98.1 m.

It's written up in an edition of the CPC Record - and I think a note about it also appeared in Descent.

There's no 'clean' hang that far though:

The original question wasn't about free hangs, but about shaft depths & the list is the Northern Caves recommended ladders, so not quite the same things. As langcliffe has already noted ladders will generally start a metre or two above the ledge you are starting from, to facilitate getting on & off, but are still a better estimate than rope lengths.

The old rigging guides used to include the pitch heights (as well as rope) - which made it much easier to work out what would reach if you didn't have the recommended lengths - but this would create some overlap on some routes e.g. Main Shaft shown as 95m, whilst Jib/Dihedral 105m. I don't know where they used to hang the ladders from, but 110m was the length given to reach their belay point, so was probably somewhere on the slope opposite Fall Beck.

Stream Passage at 26 + 32m (58)
& Vespers 7 + 12 + 27 + 36m (82) are also options.
Lancaster given as 49m.

Another Aquamole sketch suggests 49m for pitch depth, not sure which is most accurate.

Sell Gill could well also be close...

Are Electron and Megatron pitches in Trapdoor Pot the same shaft?

Looking at NFTFH the last pitch in Broken finger does not exceed or come to 50m,

Aqua mole may have a 60m pitch but as its a series of short drops where it would not be possible to fall from the top and hit the floor (I am not trying that!) I don't think that should count.

As for other caves, I can't think of any, unless we count avens.

Electron and Megatron are effectively in the same shaft but separated by a large ledge.

The drop test is an interesting idea, but I suspect that you would have to totally re-evaluate the list. Thus, for example, the ledges on Poseiden and Rat Hole may well arrest a falling caver.

Someone may have picked up on this already (I've not read all replies in detail; bit busy) but not all the examples you mention in the original post are in Yorkshire. If you're trying to get a proper list together, it might be worth clarifying whether you mean "just Yorkshire" or in the "Yorkshire Dales" (which is comprised of Lancashire, Cumbria and Yorkshire).

I'm not vying for any "pedant of the year award" here - just perhaps saving respondents' time.
