Long time back but I recall heading down slope from bottom of whatever numbered hole to arrive at obvious shored climb. This led to something – maybe a crawl – I certainly recall the way to the extensions being a crawl (possibly slightly wet) or straight on and dry leading to the ‘old’ cave..

This is Dunc’s logbook entry from 2012. It took me a while to find this so I’m posting it here for everyone’s convenience.

12th May 2012 – Pillar Holes
After a brief discussion over food/drink, we decided to opt for Pillar Holes.. Parked up, packed up and slogged up.
Mike rigged 1, ChrisSc 2 and ChrisSh 3. Down, along crawl over fissures to Breakdown Chamber, where we headed back and then along the scrotty crawl that lead to the extensions. Ended at Rift Climbs, Mike headed out for a SRT-athon, I waited for everyone else to go up then assisted by tying bags and helped push them up the climbs.
I headed out as I felt like I wasn’t 100% fit.

From what the other four said, there was in-situ rope going up, short traverse then down a pitch with an in-situ rope, down a choke and drop (with rope) into a passage which became stoop/walk to the head of a 22m pitch,
ChrisSh recounts his experience “I traversed over two easy holes to find no way past a third – they all descended the 22m pitch. I looked around for bolts or spits, didn’t see anything obvious. There were quite a few naturals around, but they’d probably make it quite an awkward get-off.”
At this point everyone headed out and went for a civilised cup of tea and food in Ingleton.
