Rumour has it that Cromford Hill was closed on Fri - some hole had opened up and when they stuck a camera down it revealed a large void beneath the road.  Anyone been for a poke yet????

How interesting. That's quite a hole. I'm sure AR will have an opinion on this...;)

.... and Terry Worthington told me about it on Friday when he came over to pick up the "magic ingredient" for making his bloomery furnaces! Haven't been a for a look myself, and I need to do some poring over barmaster's maps to try and work out what vein it's on....

There's a major vein just to the west, assuming the hole is where I think it is, though I've forgotten the name of it now - I'll get back on the Old Maps site now. OK - just been on - is it Dragoneye Vein? And are those chunks of fluorspar in the infill, or just some other orange crap? ;)

After a good squint at the barmaster's map, google earth and OG's pictures I've got a strong suspicion that  this is the fill on a run-in shaft onto Cromford Sough moving.

The hole's further upstream of the Bedehouse vein branch, which is the source of most of the current flow from the tail.  I'm more wondering if the blockage in the main sough has shifted, but  given the air quality drops off pretty badly beyond the junction, (to the extent that you'd be very lucky to get to the blockage without breathing apparatus and very stupid to try in the first place) it's an unknown quantity.  I also noticed on the barmaster's map that there was a collapse in the road in 1926, apparently onto Bates Sough.

According to the Matlock Mercury, Severn Trent are claiming it's just due to a burst water main...

They're being dragged kicking and screaming into the metric age...    ;)

I'm not sure what "60 metres squared" means; if it's 60 m by 60 m it's a sizeable cavity, and even if it's only 60 m2, it must still be apporoaching the size of the stuff they have on Mendip... ;)

I loved this sentence: "The hole measures approximately one metre in diameter and is about six feet deep."

Whats wrong with that? I always order timber in mix of old pence and new pence. 4m lengths of 2 by 4 etc etc. (y)

Aah, but the 2 by 4 is a descriptive term, rather than dimensional, so that doesn't count!

Of course they do. It's their job. The Matlock Mercury wouldn't be the same otherwise  ;)

I wonder how much bigger this hole might be after 24 hours snow-melt has added to the water-main/collapsed shaft conundrum...?
