Spot How Gill copper mine in Eskdale was worked from around 1850 for about fifty years and, at its peak, was the workplace of up to fifty miners. The copper ore they were seeking shows as a green-blue trace on the rock, a colour familiar to anyone who has seen Copper Sulphate in a school chemistry lab. The mine has long since been abandoned but the levels are accessible with reasonable care, and some wooden staging is still in place in the upper levels.
We returned via the picturesque Jubilee Bridge over Hardknott Gill and then Wahouse Bridge over the River Esk. Ordinarily these woods and valley would justify a hike in themselves.
I’ve not been underground and out of daylight for many years (except to tourist mines and caves) so this was a rare treat - thanks to Samuel for being my guide.
