Geologist Colin Devey embarks on a sweeping expedition across the European continent, tracing the geological forces that have shaped its dramatic landscapes over billions of years. From the ancient, rugged terrain of the Scottish Highlands to the bustling, industrial heart of the Ruhr region, Devey uncovers the hidden history of the land beneath our feet. Through his eyes, we witness the collision of tectonic plates, the birth of mountain ranges, and the slow, relentless march of time that has transformed the face of the earth, revealing a world that is as dynamic and ever-changing as the life that inhabits it.
