I saw an unusual picture on Facebook, showing part of Dartmoor in Devon. it's like a volcano. It's taken from an aeroplane with new technology called LiDAR - using a laser reflected from the ground and water surface (without vegetation). "I'll look for that sort of image of Cornwall," I thought. Here's the Clay Country I found. The ground is rough. From a satellite you can see the white clay. With LiDAR you can see the slag heaps and pits.
