Map of the Gwydir Forest 1:5,000
Posted: 01/07/2012 18:41:00 Reply | Quote I'm going to order a 1:5,000 map of the Gwydir Forest. These are printed to order and it will be 80cm x 80cm, i.e. covering a 4km square. It will cover *most* of the mines of the Gwydir Forest, with a couple of exceptions, the most prominent being Klondyke. The coverage will extend far enough south east to include Aberllyn; south to the Coed Mawr Pool deep adit; and west to Pandora. The map will, obviously, include the 'central' Gwydir mines such as Hafna, Parc, Llanrwst, Cwffty etc. So why am I mentioning this? Simples: the more I order, the cheaper they get. So, would anyone be interested in a copy? Dependent on numbers, I'd expect the price to be in the region of £20, slightly below if a lot of people want them. Postage can probably be arranged, but given the size, I'd prefer to hand them over in person / pass them on via someone. Anyone interested? I'd like to place the order in the next couple of days, so early responses would be appreciated. List: Van dtyson IanA Daz -- Filling space until a new signature comes along...

Posted: 02/07/2012 09:27:42 Reply | Quote No problems. One thing I should make clear - the map will only have the mines indicated on it as per the OS data - however, looking at the 1:25,000 scale map it appears that many shafts and adits are already marked. I am (slowly) working on a list of grid references for adits (and ultimately also shafts) and intend to verify these over the summer by GPS so they can be plotted if wanted. I'll circulate the grid refs to anyone who wants them as and when they're updated so maps can be annotated if required. I anticipate this being an ongoing process, so inputs from others would be welcomed! -- Filling space until a new signature comes along... IP: 81.130.77.115 |

I would be very interested in these to verify/correct the grid references in Jeremy Wilkinson's Gazetteer. (I suspect that many of his Gwdir Forest references came from Bennett and Vernon.)

Posted: 02/07/2012 14:49:07 Reply | Quote Dave, I suspect that OS data is OS data and that the 1:5k will show the same as the 1:10k - but twice as big! That said, the extra size should make the map a bit more usable and easier to mark the mines on once their position has been verified. Curiously, the 1:10k map would be considerably more expensive, although it would - of course - cover a wider area (this will be the reason for the additional cost). There's not a lot of difference in price between the 1:5k printed at 80cm x 80cm and the 1:10k printed at 40cm x 40cm! In terms of data / grid references: I've got a series of grid references from various sources, the AN database being the primary source. That currently numbers 101 locations, a few of which have more than one grid ref (e.g. Parc's various adits) and several of which have more than one name (I've combined the entries where the grid refs are identical albeit this may be subject to change). Wilkinson's grid refs seem to include a lot of duplication, in that there are entries for more than one name of a particular mine (and indeed this is referenced in the data). This is entirely understandable but does cause some some issues with interpreting the list. What I intend to do is to refine the list I've got by going through Bennett & Vernon's volumes and attempting to identify the various alternative names; and the sites that should still be combined into one. My initial thinking is that where workings were operated together at the same time (through the merging of leases etc.) then they would be considered as the same mine, albeit with the original adits / shafts identified separately. However, where workings were broken into later by a different mine then the mines would remain totally separate (e.g. Parc would not include Llanrwst). Once I've got that list generated from a 'desktop' study, it can start to be checked against the physical remains on the ground - and the grid references checked and brought up to 8 digit accuracy (e.g. SH 7804 5910 etc.). The aim will be to list the various adits/shafts against the mine they belong to - a very simplistic idea, I know, but until the problems raise their heads, it's impossible to deal with them. I have a suspicion that the master map is going to have to have lodes on it as well, which is going to be a severe test of my appalling drawing skills! -- Filling space until a new signature comes along...

This is entirely understandable but does cause some some issues with interpreting the list. True. Jeremy Wilkinson's starting point was the Home Office lists of mines, so he has one entry for each mine name appearing in the list. He then put grid references to them where he could. The grid references are not always correct as in many cases he was measuring from the 1st and 2nd edition 6" maps of 1890 and 1901 which only have lat/long markings on the margins. I've tried to cross-reference different names at the same grid reference, though I've not completed this task. (I have a data checking program that alerts me to multiple entries with the same grid reference but haven't got round to generating the cross references from that yet.) The underlying problem is that we have sites which had different names over their working lives, names that got applied to different sites over times, sites which incorporated other sites or split up, mines for which we know the names but not the locations and locations (very often trials) for which there is no (known) name. There is also the problem of different spellings or variations of the mine name. It's a real can of worms. As far as Vanord's project is concerned I suspect the best approach would be to produce a list of physical features on the ground (i.e. every shaft and level shown on the map or found on the ground) with their grid references and only name them where there is a definite association with a particular mine.

Posted: 03/07/2012 12:17:11 Reply | Quote Indeed. Where Wilkinson gets troublesome is where there is a mine which has had two names and the grid references are slightly different (which may be entirely reasoned) - in reality though, there is just the one site on the ground. Similarly, there are other issues where one company owned more than one mine at the same time - for example 'Eagle' "mine" could be Pandora or Hafna (or others iirc), so it stands to reason that they shouldn't be organised by owner. The more I go through it, the more I'm tempted just to copy B&V's groupings and be done with it. Once I've got a draft list, I'll send you a copy. -- Filling space until a new signature comes along... IP: 81.130.77.115 |

Posted: 03/07/2012 21:37:51 Reply | Quote Can I caution against this. Modern maps show few useful details. I strongly suggest that you buy one of the 25" maps from cicra. 1885 - 1915 this will give you far more detail about old mines and locations of shafts and levels. I'll email you the master sheet showing which areas are covered. IP: 109.153.56.248 |

I use, and can recommend, Cassini maps to download 1:2500 (25" to the mile) maps from 1889 or thereabouts. They have a huge range of scales and dates. www.cassinimaps.co.uk The large (A3) ones are much better value than the A4 size. Penrhynman IP: 86.176.15.41 |
