The pit remains dry. Traces of the mill and other structures can be identified across the site, along with surviving tramway formations. The remains of a steam-powered Blondin system are present, including its collapsed masts. ***

This small open pit commenced operations around 1830. Material was initially lifted by chain incline to a mill situated west of the pit, though a Blondin ropeway later replaced this system. The finished slate traveled via the lower Fligwyn incline to reach the Nantlle Railway. Some waste was deposited on the opposite side of the incline. At its peak, the quarry employed approximately forty workers and achieved annual output of around eight hundred tons. It eventually became part of the Tal y Sarn operation before closing during the 1930s.
