SN8120 : Waterfall on Afon Giedd

taken 15 years ago, 5 km NW of Glyntawe, Powys, Wales

Waterfall on Afon Giedd
Waterfall on Afon Giedd
The rocks here are layers of red sandstone dipping towards the south. As it follows the dip the Afon Giedd (a 'consequent' stream) occasionally crosses more resistant layers of sandstone (note the two large blocks at bottom right) and forms waterfalls at these points; this is the first marked on the 1:25000 O.S. map. The pool at the base of the fall is a 'plunge pool' and the whole waterfall is slowly retreating upstream, leaving behind a gorge (bottom right of photograph). On meeting the limestone further south the Afon Geith mysteriously disappears underground at the base of a cliff.
