caption_attribution_description: English: Peakshole Sough. A view of the sough (and vein) which was constructed to drain Wall End mine in the late 1700s. An inscription reads WW 1774. The sough is still in water but then dries out further in before a junction is met; one follows a small vein (Peakshole Vein) and the other passage ceases. Ladders lead up to the mine via tight stopes. The top reveals a small junction and very tight passages revealing the shafts to the surface. Mineralisation is in the form of a ENE-WSW vein and two cavity-filling pipes. This vein runs along a Namurian (mid-Carboniferous) wrench fault caused by rotation of the stress field at the time, the result of uplift of the North Derbyshire shelf. The mine contains F-Ca-Ba-Pb mineralisation.
context_page_description: A sough is an underground channel for draining water out of a mine. Ideally the bottom of the mine would be higher than the outlet, but where the mine sump is lower, water must be pumped up to the sough.
