Summary edit

Description
English: Cerrigypenrhyn and the Dyfi Estuary The spit at Ynyslas, north of Borth, forms part of the Dyfi National Nature Reserve. It is a good example of a sand spit built upon a gravel base, but it is also important because it is possible to show that a similar feature has been in existence here since about 6500 BP (Before Present). The southern part of the spit is dominated by a shingle ridge upon which there has been some accumulation of sand. The central part of the spit is dominated by vegetated dunes, whereas the northern end forms a low sandy flat upon which there are some small vegetated dunes. The behaviour of the spit seems to be related not only to the general tendency in Cardigan Bay for sediment to move northwards, but also to the patterns of water movement within the lower Dyfi estuary. http://www.jncc.gov.uk/pdf/gcrdb/GCRsiteaccount1887.pdf
