There is still a lot of industrial archaeology left on Grassington moor. Whilst walking and exploring on the moor I heard the echoes of the hard toil from the men and children who worked in the leadmines. Around Yarnbury there is enough to explore and then around the chimney there is a lot more. We are very lucky to have it on our doorstep.
In the first picture, the larger hole is the main shaft and the smaller hole behind is the access shaft. Imagine a pit head winding gear over the main shaft to remove ore and a ladder peeping out of the smaller hole for the miners to go underground.
The condenser flue runs from the Cupola Smelt Mill to the Chimney. This shaft serves two purposes: Firstly to take noxious mercury and sulfur gases away from the workers at the Smelt Mill and secondly allow lead particles to settle out of the cooling gases. Periodically boys would be sent up the shaft to sweep out the lead partilces.
