In the Foel Drygarn prehistoric quarry stone has been taken from at least four scree and blockfield locations associated with several different rock types.
In many posts on this blog I have referred to the disputes concerning the "monolith quarries" at three places: Carn Meini (Carn Menyn), Craig Rhosyfelin and Carn Goedog. The first of these was accepted as real by many archaeologists for the best part of a century, having been promoted in the writings of HH Thomas, Richard Atkinson and others and then "adopted" by Darvill and Wainwright in association with their "healing stones" hypothesis. It took a knock when Bevins and Ixer suggested that most of the spotted dolerites at Stonehenge had probably not come from there at all, but from Carn Goedog. Together with Parker Pearson, the two geologists have been instrumental since 2010 in suggesting that the petrology of bluestone monoliths and debitage at Stonehenge points to two major sources -- Carn Goedog for most spotted dolerites, and Rhosyfelin for the foliated rhyolites that occur in collections of fragments found in Stonehenge digs. (There are no Rhosyfelin standing stones.) They decided that there must have been quarries at those two sites, and of course, confirmed their ruling hypothesis by finding them, much to their own satisfaction.
As I have pointed out on multiple occasions on this blog, the evidence of actual prehistoric quarrying at those three sites does not withstand scrutiny. The "evidence" is so flimsy as to be laughable, and the conclusion has to be that the three sites display multiple features that are entirely consistent with the operation of natural processes over the course of many thousands of years of oscillating climate. That having been said, I would accept that the rock outcrops at Rhosyfelin might have been used by hunting parties over thousands of years for the provision of sharp-edged disposable cuttiong tools suitable for skinning animals and carving meat. Also, I would accept that the two spotted dolerite "quarrying" sites have been used by local farmers within the past 300 years for the provision of stone gateposts -- as indeed have other Preseli tors. And the deacons of the local nonconformist chapels have also taken many cartloads of dolerite blocks for the provision of "posh" facades on their chapels. (This was documented by my late friend Dyfed Elis Gruffydd in Welsh language publications.) The stones were NOT taken because they were supposed to be "sacred" or spiritually siognificant......
So let's get serious. There are three candidates for REAL prehistoric stone quarries in Mynydd Preseli, excluding abundant small pits and hollows all over the upland landscape that might well mark the positions of large stones used in local prehistoric stone settings. The locations are Bwlch Ungwr, Cnwc yr Hydd and Foel Drygarn. The small feature at Bwlch Ungwr, discovered by Hugh 360, is worthy of further investigation. I have mentioned in on this blog already. Much more impressive is the quarry pit on the summit of Cnwc yr Hydd, near Waun Mawn, and the string of linked pits on the slope below. I have given these plenty of space on this blog, for example here:

The Cnwc yr Hydd quarries are prominent features in the landscape, but in all the publications by Parker Pearson and his colleagues about Waun Mawn, they are completely ignored -- in spite of being located within a few hundred metres of their infamous "lost circle" of standing stones. Exposures show that these quarries have been used for the provision of slabs of meta-mudstone or foliated rhyolite suitable for domestic and farm buildings and stone walls. Transport of the slabs downhill in open countryside was very easy. My guess is that the quarries are all modern -- exploited within the past 300 years. There is nothing to suggest prehistoric use.
This leaves us with just one demonstrably prehistoric quarry -- at Foel Drygarn, close to the summit of the hill. In this case there is nothing to demonstrate modern use, and indeed it would not make much sense for local farmers to collect rubble from here, given its abundance across the countryside lower down.......
The quarrying activities have been quite extensive here -- there were at least four distinct areas of exploitation. These are shown in my various publications on this blog, for example:

The quarries are probably not Neolithic, since the main activities on this site were apparently concentrated in the Bronze Age (with the construction of three massive burial mounds) and in the Iron Age (with the construction of the fortified "village").
Nonetheless, there are some significant features of the Foel Drygarn quarrying complex:
1. The presence of suitable rock resources was a prime determinant in the location of the human features on the site -- namely three burial mounds, fortified embankments and a tribal village with maybe a few hundred inhabitants. This supports what Stephen Briggs has concluded from his studies of other prehistoric features elsewhere in Wales.
2. The targetted rock resources were small and manageable slabs of broken rhyolite, dolerite and meta mudstone. The quarrymen were NOT interested in megaliths or monoliths.
3. The slabs were almost all capable of being carried by one man or by two men working together.
4. The exploited rock resources were not rock faces but scree slopes and blockfields created by prolonged periglacial activity during the Quaternary.
5. All the collected rock slabs and blocks were collected within 60m or so of their places of use. Many were carried uphill for about 20m -- this effort was clearly preferable to the effort of carring in other rocks from external sources. In cost / benefit terms, the effort was worthwhile.
6. There are abundant and distinct physical traces of the quarrying activity -- extraction pits, waste mounds and ridges, and haulage trackways. In places so much scree has been removed that the rock face beneath has been exposed. There are no traces of tools, because none were needed.
7. I have estimated that c 14,000 tonnes of rock debris has been moved on the summit of Foel Drygarn. Some will have come from the immediate proximity of building or defensive work within the confines of the Iron Age village, but most must have come from the quarries.
8. Adjacent to one or two of the dolerite outcrops there are litters of large boulders and slabs (of bluestone monolith size!) that have simply been left behind while the quarrymen have carried away all of the smaller clasts for use in the burial mounds or fortified embankments.
So what are the lessons for those who insist that 80 Stonehenge bluestones were quarried from the living rock with the use of wedges and hammer stones, and transported all the way to Salisbury Plain thousands of years before Foel Drygarn was occupied and exploited?
There is a wonderful irony here. The one place where there is hard evidence of prehistoric stone quarrying is completely ignored by mainstream orthodoxy because it doesn't serve the Stonehenge origin story. At Foel Drygarn we see genuine, empirical evidence of prehistoric stone working in the Preseli region -- with the Bronze Age and later exploitation of local stone for highly practical, manageable architectural features. This system fits standard technological expectations perfectly:Local Scope: The slabs were extracted to build immediate, regional structures like the defensive walls of hillforts (such as Carn Alw or Carningli) or the burial cairns dotting the hills (such as Carn Briw or Foel Feddau).
Proportionate Scale: The stones were sized to be manageable by a local community working within the physical constraints of their immediate neighborhood. Common sense prevailed.
Visible Infrastructure: Unlike the alleged Stonehenge quarries, this practical exploitation leaves behind clear, unambiguous traces of extraction and use that do not require speculative ancient psychology to explain.
By completely sidelining this genuine prehistoric quarrying tradition, mainstream archaeologists expose their own confirmation bias. They ignore a real, visible, and logical stone-working evidence right under their noses while spending millions of pounds trying to prove that natural, frost-shattered rock faces at Carn Goedog and Craig Rhos-y-felin are high-tech Neolithic megalith production lines.
This selective blindness confirms that the promoters of the orthodox narrative are not interested in the actual, messy, practical reality of prehistoric stone use in Wales. They requires a pristine, monumental, long-distance fantasy to keep the "sacred transport" myth alive.............. How sad is that?
