Sink above Shooting box aven, Birks fell, Yorkshire
« on: July 17, 2021, 09:33:35 pm »
I went for a walk today, parked at Buckden, with the aim of getting to an area of limestone on the opposite side of the hill. I didn't manage to quite get to the area of hillside I wanted to. On my way back down I had a little bit of a look around when I came back down to the limestone level. prodding bits of ground with a crowbar, and drinking enough water to drown a cat.


having no real idea where the caves were underneath, despite Kevlar handily scanning me copies of northern caves and an OS map marked up with all the cave entrances. I stumbled across the sink at SD 93193 76801 which on closer inspection at home appears to be above the aven at the end of the Shooting box series. Looking into the drier part of the sink, it appears as though there is some black space beyond. I had no way of blocking up the entrance so I didn't start to attack it with a crowbar, knowing i'm committed to a trip in Derbyshire tomorrow.

According to ULSA Explorations Journal II, in 1988 "a little digging through the collapse exposed a drop down through boulders to a 20ft (6m) section of passage that ended at a very low duck which was not forced."

Cavemaps http://cavemaps.org/data/ has gpx/js/json/kml files for caves in the three Northern Caves books.

I load them into OSMAnd https://osmand.net/, instructions on my web site: https://wylie.me.uk/cgi-bin/blosxom.cgi/2019/05/06#osmand-caves

HI Alan, not sure where the coordinates I have on my GPS came from, but i've got quite a few of the dales caves on there, I knew that I was 200m away from Birks fell entrance when I was at the Sink, but knowing the cave is nearby is not quite the same as knowing part of the cave is 10-30 to 50m away under the ground. I think I got the GPS locations on after a few drinks.

According to ULSA Explorations Journal II, in 1988 "a little digging through the collapse exposed a drop down through boulders to a 20ft (6m) section of passage that ended at a very low duck which was not forced."

Thanks molerat, sounds like they had a good time, I guess it must have been walled up to stop lambs and sheep playing lemmings.

I think I might need to visit Birks fell, you seem to love the place, it does sound like a good trip.
