In episode four, Caroline meets Lancashire-based writer Carys Davies, whose phenomenal novella West is set in the vast, wild landscape of the American Midwest in the middle of the 19th century. In this book about exploration and walking into the unknown, the sense of an undiscovered landscape offers remarkable parallels with Weardale.

Local writers Susan Nicholson and Chris Powell of the North Pens writing group also discuss the book and its resonance with the area, while Chris Scaife, a caver and explorer, talks about the instinct for exploration and the excitement of visiting a place that how not yet been uncovered.
