A 2.8 km river now runs the length of the valley, cut so its bed always falls downstream, with pools, riffles, gravel bars and boulders that break the surface.

Open groves of coppiced oak, about 47,500 stems with shrubs beneath, cover the foothills above it.

Where the asphalt ends, a cordon line crosses the valley: concrete teeth, wire and radiation signs. A dirt track runs on past it to the ruined outskirts of Shar.
