Sgwd Isaf Clun-Gwyn, Waterfall Country, Brecon Beacons, Wales.
A 30 second exposure of Sgwd Isaf Clun-Gwyn, which translates as 'the lower fall of the white meadow'. These falls are the middle of three celebrated falls on the Afon Mellte (River Mellte) in an area known as 'Waterfall Country'.
Waterfall Country is an area loosely defined, but generally includes the group of falls on the Nedd Fechan, Pyrddin, Hepste and Mellte rivers, all of which lie in the country between the villages of Pontneddfechan and Ystradfellte in the southern part of the Brecon Beacons National Park. Most of the falls occupy locations designated as sites of special scientific interest or as special areas of conservation.
Virtually all of the falls occur on tributaries of the River Neath which occupy valleys that have been deeply incised into the landscape. It is suggested that overdeepening of the Vale of Neath by glacier ice during the succession of ice ages has resulted in these tributaries cutting down into their own beds as they adjust to a base level lower than in pre-glacial times.
The underlying geology is a generally southerly dipping succession of Carboniferous age sandstones and mudstones assigned by geologists to the Marros Group and formerly referred to as the Millstone Grit Series. Preferential erosion whereby the less resistant mudstones have been more readily removed by the passage of water, often following various forms of weathering, has left sandstones forming the lips of the falls. The siting of individual falls is closely lnked in many cases to the presence of northwest-southeast aligned faults which have brought different lithologies into proximity.
