GeoGraph - photograph every grid square

The signpost points in two directions - one is a footpath over a ford (and recently dismantled foot bridge) to nearby locations in Brynamman and the other out onto the Black Mountain.

The latter is actually shown as a road that traverses the mountain on old maps, being presented as an equal to the tarmac road that runs in parallel not too far away. The old road's path can be followed throughout its course both on maps and on the ground, arriving at SN7019 : Old trackway, though these days a nearby sign warns that no motor vehicles are allowed to use it!
