The influence Britain's geology has had on our daily lives is profound. While we may be unaware of it, every aspect of our history has been affected by events that happened ten thousand, a million, or a thousand million years ago. In 'Walking the Bones of Britain', Christopher Somerville takes a journey of a thousand miles, beginning in the far north, at the three-billion-year-old rocks of the Isle of Lewis, formed when the world was still molten, and travelling south-eastwards to the furthest corner of Essex, where new land is being formed. Crossing bogs, scaling peaks and skirting quarry pits, he unearths the stories bound up in the layers of rock beneath our feet, and examines how they have influenced everything from how we farm to how we build our houses, from the Industrial Revolution to the current climate crisis.
