S ummary Investigations into former lake basins in the region to the north of Capel Curig (SH 721581) in Caernarvonshire have revealed deposits of Late‐glacial age. Pollen analysis of the deposits permits subdivision of the sequence into the standard Late‐glacial zones I, II and III together with some sub‐zones based upon recurring pollen assemblages. Some of the ecological implications of these assemblages are discussed, in terms of vegetation, climate and soils. High Rumex * pollen values characterize pollen zone I. A wide range of herbs and Betula pollen dominate in zone II. Zone III is characterized by high Artemisia pollen values. A transition zone III–IV is included to cover the Empetrum and Juniperus pollen peaks, prior to the rapid rise in Betula pollen values in zone IV.
