SO3220 : Llanfihangel Crucornau End Moraine
taken 16 years ago, near to Llanvihangel Crucorney, Monmouthshire/Sir Fynwy, Wales
Llanfihangel Crucornau End Moraine
This sweeping grassy bank marks the end of the road for a branch of the Usk Valley glacier. It is in fact a huge terminal moraine which stretches completely across the valley and stands as much as 125ft above the floodplain of the Afon Honddu to its north. Prior to the last ice age the river probably flowed south along the valley now enjoyed by the tiny Afon Gafenni to join the Usk at Abergavenny. This spectacular feature now prevents that.
