This mound is a slag heap from the Somerset Coal Field, which was an unexpected industrial outpost set in the heart of the West's countryside, and which only ceased coal production in relatively recent years. Indeed, much of the traffic on the Kennet and Avon Canal originated from the Somerset Coal Canal ... and for a time passed up the Wilts and Berks through Melksham
Perhaps Silbury Hill is just a pre-historic slag heap?
