This striking collage is a visual chronicle of residents’ fight to prevent Tirpentwys Woods, near Pontypool, from being turned into a quarry. Known locally as ‘the Canyons’, the area was an opencast coal mine from the 1870s to the 1960s. For the last 50 years, however it has been reclaimed by nature and is now a wooded cut through uplands with a lake at the bottom. It is a classic example of the ‘greening of the valleys’ that has accompanied de-industrialisation in many parts of south Wales.
