Pitlamp said:Muddy Funkster said:Time machine is classed as a passage but it has the feel of a chamber. For clarification do people know what all the current records are? Looks like the current definitions state
Biggest chamber = Frozen Deep
Biggest shaft = Titan
Biggest passage = Time Machine
Biggest vertical entrance = Gaping Gill ?
Biggest horizontal entrance = Porth -Yr - Ogof
Longest constricted entrance = Daren Cilau
Most remote location = Spade Runner
Longest Sump = ?
Anyone else care to correct these or add to the list?
I'd not necessarily agree with the above, especially as you give no evidence.
In case it helps, I think the longest sump in the UK is probably that one in Ireland which Artur was exploring before he died not long ago. I can't remember it's correct name without looking it up but there was a piece on it in Descent at the time.
