Countrystride #9: Derwent Water: Creation of a landscape

 ...in which we walk Derwent Water's wooded west shore from Manesty to Brandelhow Wood with National Trust ranger Roy Henderson, who talks to us about the valley's industrial past and today's management, before organising a search party for a missing labrador. At Crow Park we're joined by Dr Christopher Donaldson to take a long view of the Picturesque and the birth of the worldwide conservation movement.
