Buckland Hill near Bwlch

The A40 Brecon/Abergavenny road passes through a gap in the hills at Bwlch (Welsh = pass) where a spur of the Black Mountains/Y Mynyddoedd Duon reaches across the broad valley of the River Usk/Afon Wysg. It is probably the presence of the hard-wearing sandstones of the Brownstones Formation seen amongst the bracken in this shot which account for the presence of Buckland Hill. It would have been over-ridden by the Usk valley glacier moving southeastwards through here during the last Ice Age. The area is now access land.

Views from Buckland Hill

A line of lichen-encrusted low sandstone buttresses decorate the western edge of the hill immediately south of the village of Bwlch (Welsh = 'pass') on the A40. Emerging from a bracken-covered slope scattered with oaks, birch and hawthorns they afford an excellent viewpoint for the distant ridges of the Black Mountains/Y Mynyddoedd Duon. These same purple/brown rocks (the Brownstones Formation within the 'Old Red Sandstone') also form the larger part of the Brecon Beacons to the south. The prominent spur of 'Crug Hywel' can just be seen in the distance on the right SO2220

Bridleway to Cefn Moel

This public right of way runs between bracken banks across slabby Old Red Sandstone bedrock ('Senni Beds' for the initiated) to join the Beacons Way running north from Bwlch.

Track at Penlan

This track leaves the gated minor road between Bwlch and Felindre/Cwmdu at a hairpin above the farmstead of Penlan. The status of the track is unclear although the bracken-covered hillside to its left (west) is depicted as access land by OS. Walkers can gain access to Cefn Moel from here though as the sign suggests, motorcyclists are bidden not to do so.

Quarries at Tremynfa, Bwlch

The east facing slopes of the hillside north of Bwlch hide a number of small outcrops of the Devonian age 'Senni Beds' or Old Red Sandstone which has been quarried in several places in the past for building stone. Bracken has now claimed these slopes, designated as open country so access is available.

This close-up shot taken in the disused and overgrown quarries in the hillside north of the village of Bwlch reveals the rich colour of this stone which is widely used for building locally.

Glacial overflow channel

Just west of the village of Bwlch, the modern A40 crosses this depression on a 5m high embankment. It was at this point that glacial Llangorse Lake/Llyn Syfaddan overflowed into the Usk catchment. It currently empties into the Wye via the Afon Llynfi but that northerly exit was blocked towards the end of the last Ice Age and the dammed waters found an outlet (at a height of 190m) to the south instead.
