Some slate material was extracted there in the 1960's to the early 1980's by 3 different persons to my knowlege.
It was worked prior to that sparadicaly. Quite overgrown with trees now, remains of the shed and some domestic junk is all there is to see. Not big at all and the workings was basicaly just extracting what slate there was to be seen on the surface.
The most recent was for making slate craft etc. I do not know what it was called though.
Nice walk down thrugh cwm Cynfal on a dry day. Or walk up the track at the bottom of 'allt goch' by the bend about 100 yds to get to the quarry.
There is another quarry further down the main road opposite the Llechrwd caravan site. It is called 'Braich Goch. It was last used for material for slate craft.
Bellach dim ond swn y gwynt yn chwibian, lle bu gynt yr engan ar cynion yn tincian.
