Cerrig Calch

Some of the "cerrig calch" (lime stone) that gives Pen Cerrig Calch its name. The whole top is scattered in lumps of this bright white rock of all sizes. Pen Cerrig Calch is the southern end of the western Black Mountains ridge. Sugar Loaf (SO2718 : Sugar Loaf) and Blorenge (SO3013 : Blorenge from Abergavenny, Monmouthshire) are in the background.

The summit and the ridge linking it with Pen Allt Mawr (SO2024 : Pen Allt Mawr summit) pretty much fills this square. The vegetation is scrubby grassland interspersed with those rocks. It's a lot drier ground than most of the Black Mountains.
