Date	19 March 2011
Location	Gyrn Wigau / Caseg valley, Carneddau	SH 65202 66723; 53.18046°N, 4.01853°W
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.
