Raven Mine
« on: March 07, 2018, 10:58:21 pm »
I'm thinking of doing a trip down Raven Mine at Monyash in the near future. l have the grid reference, but if anyone can give any extra info to aid finding the shaft it would be appreciated.

Also, is the shaft lidded or covered, or is it open? If covered, what's it covered with? Does it need a spanner?

Any info on the place at all would be appreciated.

Thanks Al, that's a brilliant map

I haven't got a copy of COPD with me at the moment but I thought the map in it showed Raven Mine on the same side of Fern Dale as Freezeland Mine. It looks like the guide is wrong - good job I asked.

It has a grill covering it - i can't remember using a spanner!
It is on a little mound of earth, that is next to a dry stone wall. Well worth a visit!

On reflection, I've asked for the map to be removed as it may be in breach of copyright.
Sorry about this, Madness - I hope that you've got the details now.

It's also on the DCA cave registry, probably best to view in Google maps rather than OS, then you get satellite imagery and can see the walls.

https://thedca.org.uk/dca-cr/registry/sitedetails.php?id=188

I went the other year, but we were light on rope, ended up not doing as much as although you shouldn't trust any of the ladders in there. I think I remember the last ladder we saw was very sparce on rungs!

The map that Al posted and the Derbyshire Cave Registry point to the same location. COPD suggests that to be the location of Eagle Mine. I trust Al more than COPD, which has the wrong grid ref. for Raven Mine and the wrong position on the map. Is anyone keeping a log or COPD errors for when a new edition is planned?

The Cave Registry map shows Eagle Mine as a yellow pointer not very far from Raven Mine.

There is a feedback form link on the Registry site, for submitting corrections.  A lot of locations are not very accurate, so updates are always welcome. Entrance pictures are also very much welcome for the revived peakdistrictcaving.info site.

The registry data will feed into any future COPD editions.

The "Raven" Mine I went down years ago was in the middle of the first field
below Eagle Mine .It never fitted the descriptions in the Books . A great potential
dig in there as well.

A perfect opportunity for me (as DCA Cave Registry Secretary) to ask folks to send in accurate grid refs (and entrance photos) for as many sites as possible, whenever possible. We can only use the data we have, and it's impossible for us to go around every catchment checking every reference for accuracy. Grid Reference Finder is excellent when the entrance to somewhere is obvious from their satellite view, but entrances within trees (especially lots of entrances, like Stoney Middleton) are very difficult to log without accurate GPS refs. If folks have these units, and you regularly walk in areas of interest, please log sites and send them in, and then I can update the registry immediately.

I've just downloaded an App for my Iphone which gives a grid reference for the phone. I think it may be useful.

NB.  Lat Long is also fine of course - (WGS84).

With phone apps it is best if they give you some indication of the accuracy.

Unfortunately you still can't trust GPS readings under trees, so take several...

As Alan has removed the map here is a new one showing a way of walking to Raven mine if you park in the layby at the top of Lathkill dale by the toilets. (Just down from Google maps and memory.....)


And closer of the entrance mound....

Alastair - I think you will find the rungs are all there, just in a pile at the bottom of the pitch!
Well worth going back to, At the bottom of the missing rung pitch you climb over a blind pit then crawl a little way - a climb up takes you to loads more stuff. An interesting mine cos you have to play 'spot the mine' as it seems to be almost all natural!

Thanks to everyone for the information.

We had a trip down Raven Mine last night and it is an interesting place with lots of dig potential. It could do with a bit of engineering work though. A few new anchors would go amiss. I tried not to notice the badly stacked deads behind the matting!

Access query? Is it best to approach Raven Mine from Fern Dale or another direction. I was undertaking a reccy yesterday from Fern Dale and I could see location of Raven Mine from the field I had crossed and there was a stepping-stone crossing point in drystone wall, but wall was topped with barbed wire! Many thanks, Paul.

I thought Ben had dug it to death in the higher up stuff! The very very high up stuff is pretty close to surface from what I remember and the main interesting lead was the flooded shaft that you step across.

If I remember it correctly, the passage way that goes off at the 'eyehole' away from the flooded shaft has a free-climbable raise (up flowstone). At the top of this is a flat passage heading off somewhere. It's been dug/is being dug by someone. There's other natural passage that's well choked, that might yield something.

Yup - Some of us Orpheus lot had a (quick) look at that particular dig (myself included) some time ago, probably early in 2017. We removed some of the floor and managed to push forward a couple of meters, to a point we could get a better view of what lied ahead, but the consensus was that it didn't look to inspiring. We meant to go back and push it a further, but got distracted with other things.

---

The flooded Shaft below the eye-hole is has also received some attention by Orpheus over the last few years, on and off, as it depends upon the water levels. I've not been involved with this particular project, but if I recall correctly, it does drain away, and I'm pretty sure the depth has been extended a little. I'm fairly certain the digger(s) do periodically check the water levels with a view to continue digging. I'm think they've had the odd poke around elsewhere in Raven too.

Anyway, if anyone is interested, pm me, I can put you in touch with someone who can give you more info.

As Pipster already pointed out, the wet shaft below the eyehole has been extended.it was noticed by the diggers that there was a false bottom to the shaft, so we collapsed it and found that there are possibly two ways on... Water levels stopped play. It's an X on the Orpheus digging calendar.

Pipster, you need to get back in there with Pete :)
