Dredging up an old subject...
Mr chapman a few months ago suggested i find fatigue, i've not yet been in.
I had a few moments to spare last saturday to sample the pungent smell of the entrance. after 30+minutes we did manage to find the hole, but could have found it much quicker...
We parked near the calver crossroads and walked back towards stoney middleton.
Taking the first left turn off the main road marked as a public footpath (which is a track, only passable on foot).
Follow the track for quite a while, after the childrens playground you'll pass a wooded section on the right and then it will open out into fields again. Once you see the fields again, it wont be far till you find a stile which leads into the field. Go into this field and turn left, keeping the fence on your left keep wandering till there is a metal farm gate leading back to the lane. Turn your back to this gate so that you're facing the hillside.
When we were there, there was a petrified tree on the hillside just to the left (about 15 to 30 degrees), this lines up with fatigue pot. Fatigue is about 2m behind this tree.
(Really not far up the hillside, if you're going all the way to the top of the hill you're looking too hard).
