It's been a while since I last went into Mandale mine, so when some friends suggested having a look in I though "yeah, why not?". My previous experience of Mandale was that it was wet, and going upstream in the sough would most likely involve water to mid-thigh. Going on this, I chucked my wetsuit bottoms and a fleece top in the car instead of the furry, and some other members of the party turned up with full wetsuits.
having headed up Lathkill dale to the engine house ruins, we opened up the gate to the incline with the usual Derbyshire key and headed downhill. The incline is now very rough due to bits having dropped off the roof over the years, but back in the 1840s it was railed for tramming, and went below the present sough level. At the incline foot, where you normally meet water, there was none, and a look into the sough confirmed there was nothing more than the occasional puddle. Although I'd been told the sough does sometimes dry up this is the first time I've ever seen it do this!
So, the way on upstream was much easier than expected albeit much sweatier for those in neoprene. We passed through the large stope and crawled through to the flooded stopes, where I've previously stopped as the way on required swimming but the drop in water levels meant that with one easy and one difficult traverse, you could get on into the next section of the sough.
There's a lot of stal in the next section, including one very nice bit where it's run over herringbone arching, much like that in Spinney level. There are also covered stone drains in the floor in another section, though why is not apparent. Eventually, the sough opens out in the chamber of Mandale forefield shaft, where a stream from the upper sough runs into the shaft. Unfortunately, this was a bit smelly due to a) a dead rabbit floating in the water of the shaft and b) what looks suspiciously like sewage in the flow from the upper sough. I didn't go into the final section as it just leads to a collapse but some of my colleagues did, I hope they soak their wellies in bleach!
This is the limit of what's explorable in Mandale now but makes for a good short trip, plus the nearest pub (the Lathkill Hotel in Over Haddon) has a fine selection of ales for the after-trip thirst quencher. As mentioned, access is with a Derbyshire key and is open to anyone with BCA cover.
Follow the horses, Johnny my laddie, follow the horses canny lad-oh!
