If you look closely, on the top of the cliff to the left is Boulby Mine, which is the UK’s deepest mine at 1400 metres. It produces rock salt used across the region as a de-icing agent on the roads in winter conditions. I had actually parked the car to walk into the small fishing village of Staithes on the coast but saw this cliff and though it deserved a quick photograph. I didn’t go much closer than this with my camera to the mine or the edge of the cliff!
