Hemplands?It's a really interesting "planet caving" picture!
OK, try this. Many cavers will not have seen this cave but may be able to work it out. (I may even have used an alterntive picture of this entrance on here before but can't remember.) Anyway, I'll give clues along the way if need be. First clue; Northern Caves Volume 1.

Sell Gill ?Nope.
(You'll kick yourselves when I spill the beans, as so many of you will have seen that view!)
could it be white scar?Now you mention it, that does look quite similar to the northern end of Sell Gill Main Chamber up the boulder slope where you climb up from the stream.
But nope.
However, it is in Northern Caves Volume 2, just to start narrowing it down.
could it be white scar?
is it part of Gaping Gill?There's some large passages under Ingleborough.
OOPS! that's perhaps given the game away!
Ingleborough cave?That's not very specific . . . . .
GG has around 23 km of passages. The one in the photo is very well known!
