GeoGraph - photograph every grid square

As the road climbs north, the houses on the left side give way to the gorge of the Upper Clydach river in Cwm Du Glen.
For many months the road had been reduced to a single lane because the outside was falling into the gorge. Now drivers have a newly surfaced road and a tall stone wall that hides the huge drop-off on the other side. Even pedestrians cannot see over - this shot was taken by climbing the crash barrier.
