Description
Description Cors Geuallt is an important pollen site recording detailed vegetation and environmental changes in North Wales during the Late-glacial and Post-glacial periods. It is one of only a few sites in Britain that provide evidence for a pre-Allerod climatic oscillation, possibly equivalent to the Bolling Interstadial. The pollen record therefore contrasts with other key Late-glacial sites in Wales which show evidence for only one warm episode. Cors Geuallt is also the only site in Wales where a detailed record of diatoms extending back into the Late-glacial has been studied.
