Brecon Beacons

The Brecon Beacons National Park contains arguably the most spectacular upland scenery in southern Britain. This guide describes the enigmatic landforms that mark the outer limits of small glaciers or perennial snowbeds at the foot of the impressive escarpments in the Fforest Fawr, Mynydd Du and Bannau Brycheiniog (Brecon Beacon) areas. It also discusses some of the evidence for their age and possible origins.
