Ac cel er a tor mass spec trom e try (AMS) 14 C dates, pol len and plant macrofossil ev i dence and lithostratigraphic pa ram e ters ob tained from four Late Gla cial lake sed i ment re cords were used to study the deglaciation chro nol ogy of Es to nia. AMS dates show that the north ern part of the Saadjärv Drum lin Field was free of ice cover at ap prox i mately 14,300-14,200 cal yr BP. These ages fit well with the ice re treat es tima tions (14,700-14,500 cal yr BP) of the Otepää ice-mar ginal zone in the south and the deglaciation of the Pandivere Up land in the north (13,800 cal yr BP). Glaciolacustrine sed i ments of the Haljala and Udriku bas ins were de pos ited in proglacial lake A 1 , a north east ern bay of the Bal tic Ice Lake that al ready ex isted ca. 13,800 cal yr BP. The Palivere ice-mar ginal zone, and proglacial lake A 2 as so ci ated with it, was formed ca. 500 years later, at ap prox i mately 13,200 cal yr BP.

Reconstructions of ice cover during the time spanning the Late Weichselian maximum show a confluent Eurasian ice sheet with the Scandinavian Ice Sheet positioned between the Svalbard-Barents-Kara and the British-Irish ice sheets. It has long been suspected among glacial geologists that the maximum ice-marginal position was asynchronous, but only recently has it been possible to explore this in some detail. Dates pertaining to the ice margin of the Scandinavian Ice Sheet reveal an old (29-25 ka) maximum position along its western flank, whereas a younger (18-16 ka) maximum position has been delineated along its eastern flank. A time -distance diagram across the Scandinavian Ice sheet shows an oscillatory western ice front, as opposed to a steadily growing and decaying eastern ice margin. The largest age difference between maximum positions is as much as 10 ka between different sectors of the Scandinavian Ice Sheet. Older maximum positions of the western margin can be explained by its proximity to icegrowth centres, initial windward ice growth, efficient ice drainage in ice streams on the Norwegian continental shelf, and the continental shelf break being a barrier to further westward expansion. Younger maximum positions of the eastern margin can be explained by a very long distance between ice-growth centres and marginal positions, slow flow in a wide zone of cold-based to partly cold-based ice, and punctuated advances of low-gradient ice lobes into proglacial lakes along the extreme eastern perimeter of the ice sheet. The influence of these lakes on the glacier dynamics of adjoining ice lobes prolonged the ice sheet advance by some 1 to 3 ka compared with adjacent interlobate areas.
