Revision as of 14:12, 20 September 2015
The Hatterrall Ridge (sometimes spelled Hatterall) is a ridge in the Black Mountains forming the border between Powys and Monmouthshire in Wales and Herefordshire in England. The ridge is about 10 miles (16 km) long, and is followed by the Offa's Dyke Path. On the west side of the ridge is the Vale of Ewyas, and on the east side is the river Olchon Valley. The western side of the ridge falls within the Brecon Beacons National Park. Much of the northern part of the ridge is a broad saddleback, but it narrows down considerably further south, and especially near to Llanthony Abbey in the Vale of Ewyas to the west of the mountain. There is a large and prominent landslip on the eastern side of the mountain here, known as Black Darren, where a large slice of the rocks have fallen away from the main mass of the hill.
Peaks
The highest point on the ridge is Black Mountain (elevation 703 m), near its northern end. Hatterrall Hill (elevation 531 m) is near the southern end of the ridge. The hill is common land grazed by sheep, ponies and cattle.[1]
Geology
The hill is composed from sandstones and mudstones of the Senni Formation of the Old Red Sandstone which is of Devonian age. Numerous small quarries adorn its slopes though all are now abandoned. The shape of the Vale of Ewyas to the south and west of the ridge strongly suggests that it was occupied by a glacier during at least one ice age, though not perhaps during the last ice age.[2] The plateau was probably ice-free.
The ridge is often used for paragliding and hang gliding when the wind is from the east or east-north-east.
