SH6873 : Quarry, Garreg Fawr

taken 3 years ago, near to Llanfairfechan, Conwy, Great Britain

Quarry, Garreg Fawr
Quarry, Garreg Fawr
A disused quarry is suggested on the map, but I am sure that rock has only been won here to construct the nearby corlan since there is no track or tramway to carry away the product. The construction of the corlan in such a strategic location, close to a good supply of suitable stone is a good example of the pre-industrial agricultural economy. In the far distance, above the town of Llanfairfechan, is the much-quarried mass of Penmaen Mawr.

In fact, the two locations are linked geologically, since Garreg Fawr comprises a small offshoot of the large igneous intrusion of Penmaen Mawr. Here the rock is fine-grained and less obviously crystalline, but the British Geological Survey are certain that they are genetically linked intrusions of a quartz micro-diorite. Both localities display pervasive, closely-spaced jointing that makes the rock outcrop such a fine source of equant blocks for construction purposes.
