The Abercorris quarry (also known as Cwmodyn quarry) was a slate quarry worked between the mid-1840s[1] and the early 1950s. It was located at Corris Uchaf about 5 miles north of Machynlleth, in Gwynedd, north-west Wales. The quarry was connected to the Corris Railway via the Upper Corris Tramway which carried its products to the Cambrian Railways at Machynlleth for distribution. It worked the Narrow Vein.
