2, 3: Patrick Warren descending site 853, April 2017. At first we didn't think we'd get down this. We knew there was a shaft but the owner had poured diesel onto some rubbish to burn and so the area at surface wasn't particularly nice; plus, 'though we could see there was a shaft, it was not easy, through the rubbish, to see how we could get in. After some scratching about we found some large stones used to cover the entrance and slid them out to make a hole big enough to descend. (photos and caption: Stuart Emmett)
