Lord Hereford's Knob or Twmpa is a mountain 2,260 feet high in eastern Brecknockshire, immediately north-east of Rhos Dirion and south-west of Hay Bluff. It is two miles west of the border with Herefordshire and around five miles east of Talgarth and the same south of Hay-on-Wye.
The mountain forms part of the great north-west scarp of the Black Mountains. To the north-east lies the Gospel Pass through which runs a minor road between Hay and the Llanthony Valley. A ridge known as Darren Lwyd tapers away for about two miles to the south-east of the summit.
Walking
The entire hill is classed as open country under the Countryside and Rights of Way Act and is therefore available for walkers to roam freely across. It is almost encircled by public bridleways and restricted byways. The most well-used track is that running west from Gospel Pass (where car parking is available), over its summit and then south-west towards Rhos Dirion. A further track runs the length of the ridge south-eastwards to the hamlet of Capel-y-ffin.
Geology
In common with neighbouring hills, Lord Hereford's Knob is composed of alternate layers of sandstone and mudstone dating from the Devonian period and ascribed to the Lower Old Red Sandstone. Its lower slopes are formed from the mudstone-dominated St Maughans Formation whilst the upper part of the hill is composed of sandstone-dominated Senni Formation rocks. At the junction between the two is a prominent calcrete known as the Ffynnon Limestone.
Numerous landslips have occurred within the St Maughans Formation around the flanks of the hill.[1]
Trivia
"Lord Hereford's Knob" is the title of a song on Half Man Half Biscuit's 2008 album CSI: Ambleside. The lyrics feature the grid reference of the mountain.[2]
