Table Mountain is a flat-topped mountain at the southern edge of the Black Mountains in Brecknockshire. It rises to 1,480 ft above sea level, from the southern flank of Pen Cerrig-calch (2,300 ft). It gives its name in the Welsh language, Crug Hywel to the town of Crickhowell, which it overlooks.[1]

The summit is entirely taken up by an Iron Age hillfort,[1] with a clearly visible earth and stone ditch and rampart.[2] Crug Hywel is approached by a couple of public footpaths across farmland from Crickhowell and Llanbedr and visited by the Beacons Way. It lies within an area designated as open country over which the public have the right to roam.

Geology

Crug Hywel

The hill is formed from Old Red Sandstone originating in the Devonian period, specifically the sandstones of the Brownstones Formation, topped by rocks of the Quartz Conglomerate Group. The whole mass of rocks forming this outlier of Pen Cerrig-calch can readily be seen to dip more sharply to the south than nearby strata and is considered to be an excellent example of a translational slide.[3]
