Information

The quarry is located in the Caseg valley on the lower southern slopes of Gyrn Wigau. A short adit, whose entrance is on the level of the foot of the waste tip, leads into a small pit in the middle of the main extractive area. There seems to be some debate as to whether the workings here were known as Afon Gaseg or Dr Hughes Quarry.

Information

Afon Wen is a small tributary of the Caseg and its ravine descends down into the Caseg valley between the mountains Garnedd Uchaf and Foel Grach in the Carneddau range. A quarry track leads along the Caseg valley and at an elevation of about 700m in the Afon Wen ravine there can be found the remains of a small slate quarry. On the southern side of the ravine a small quarry and spoil heap are prominent on the landscape of Ochr Fwsoglog on the slopes of Foel Grach. The latter workings were probably for iron or copper.
