Report - Croesor Slate Quarry - April 12

[God]

Visited with Two Non-Members​

Absolute belter of a day, very exhausting, the walk in alone almost killed me! Its a maintained caving route so plenty of anchors, ropes in situe (although we took spares after a failed first attempt of someone cutting and tying a rope back together :crazy), there's a zip wire, traverse, bridge of death, ladder bridge! All made for a good day!

History​

Stolen Professionally from Wiki...

Croesor Quarry was initially worked from 1846 until 1878. From 1864 onwards, the quarry was connected to the slate wharves at Porthmadog by an incline to the head of the Croesor Tramway. After a hiatus, it re-opened in 1895 and continued in production until 1930.

In the 1960s the quarry was operated by Cookes Explosive, a local firm who used its underground chambers to store explosives. In the early 1970s it was purchased by the Ffestiniog Slate Company with a view to reopening it as a working slate quarry. Planning permission for this was not granted and in the later 1970s most of the remaining mine infrastructure was removed for use in the Oakeley Quarry, also owned by the Ffestiniog Slate Company.
