...in which we are joined by industrial archeologist supremo Mark Hatton to talk all things slate as we ascend and then tunnel deep into the fellside of The Old Man of Coniston. Picking through the abandoned remains of old working floors and tips, we learn about the long history of slate quarrying in the Lake District – an industry spread over 200 sites that yielded a range of highly-prized stone. Discussing how slate is formed, we make our way to the powerhouse, smithy and working floor of the Old Man workings, where millions of tonnes of stone were shaped into prized roofing slate by generations of miners. As we wander, we hear about the likely Norman origins of the industry; the revolution wrought by compressed air; the perils of journeying home in the snow; and the Sunday-morning miracles that collapsed caverns – and saved lives.

It would be remiss not to note that we recorded underground in the company of an experienced guide, and kitted with helmets and torches. Exploring these workings is immensely enjoyable - in the right company and with the right kit. In all cases, leave the workings as you found them. ***
