Just to clarify, is permission required to use the top entrance? I thought it was out of bounds in someone's garden. The last time I was in there was a new metal gate fitted. It was possible to get around the side of this but looked like a infill was due to be added.
Sorry, just seen that the Devonshire listing on the DCA site does not seems to have been up updated when we added the other entrances to the access agreement. I've just submitted the following text to correct that:"Devonshire Upper Entrance is not mentioned on the listing. This does not require permission to use. A combination lock may be present, if so the code will be ****. There are plans to convert this Upper gate to a Derbyshire Key in future. The shaft from surface above the main chamber and just inside from the Upper Entrance is also approved for access."
You've not been melting the rock somewhere with your latest bit of kit, have you?
A quick report. I can send a more detailed report and pictures but I tried to do that earlier on this topic and it hasn't posted, don't know why. The pack below the door at the lower entrance seems to have moved forward and down. I'm guessing surface run-off from the slope leading to the entrance. There seems to my non-engineering eye, to be no downward slumping. Some material is going down the muddy slope to the left of the entrance (looking out) that leads to the lower series but that seemed unchanged (although it looks like some hanging death in the ceiling but I think that has always been there). Went to the base of the infilled entrance shaft, I believe (behind the large rectangular block) where there are two upward chokes. The left one is jammed blocks which don't look to have moved. No sign of new debris on the floor. Slightly right is a much looser looking infill. Again, no sign of collapse but quite muddy and water has obviously been trickling down. Recent shoulder surgery (rotator cuff tear) prevented me from investigating small holes. There is still a padlock on the upper entrance gate but a hole to the left of the gate was easily big enough to allow me in.
