Based on geological and archaeological proxies from NW R ussia and NE E stonia and on GIS ‐based modelling, shore displacement during the S tone A ge in the N arva‐ L uga K lint B ay area in the eastern G ulf of F inland was reconstructed. The reconstructed shore displacement curve displays three regressive phases in the B altic S ea history, interrupted by the rapid A ncylus L ake and L itorina S ea transgressions c . 10.9–10.2 cal. ka BP and c . 8.5–7.3 cal. ka BP , respectively. During the A ncylus transgression the lake level rose 9 m at an average rate of about 13 mm per year, while during the Litorina transgression the sea level rose 8 m at an average rate of about 7 mm per year. The results show that the highest shoreline of A ncylus L ake at an altitude of 8–17 m a.s.l. was formed c . 10.2 cal. ka BP and that of the L itorina S ea at an altitude of 6–14 m a.s.l., c . 7.3 cal. ka BP . The oldest traces of human activity dated to 8.5–7.9 cal. ka BP are associated with the palaeo‐ N arva R iver in the period of low water level in the B altic basin at the beginning of the L itorina S ea transgression. The coastal settlement associated with the L itorina S ea lagoon, presently represented by 33 S tone A ge sites, developed in the area c . 7.1 cal. ka BP and existed there for more than 2000 years. Transformation from the coastal settlement back to the river settlement indicates a change from a fishing‐and‐hunting economy to farming and animal husbandry c . 4.4 cal. ka BP , coinciding with the time of the overgrowing of the lagoon in the N arva‐ L uga K lint B ay area.
