Myself and a few Durham Dales Mining Explorers many years ago struggled on hands and knees up Buckler Dale level with a ladder to climb the rise on the vein, but alas it just entered a small stope ,we attempted to clear the main level as it was making a good flow of water but progress was thwarted due to the lack of height at this point and the fact that the rock was calclted together, there is an open shaft to the south which may be associated with this mine,there seems very little documentation.
