“…Dunes formed both on the broad surface of the fluvial terrace of the River Mustjõgi and glaciofluvial delta. The sites are located outside of the Otepää (Linkuva, Zelčs et al, 2011) ice marginal zone, but within the Haanja (Gulbene, Zelčs et al, 2011) zone (Kalm et al, 2011). The age of the zones is thought to be between ca.…”

“…Dunes are distributed on the surface of a broad glaciolacustrine plain formed by melting of the Burtnieks ice lobe (Zelčs and Markots, 2004). The glaciolacustrine sediments formed in the ice-dammed/proglacial (Smiltene-Strenči) lake, which presumably existed between the Linkuva and Valdemarpils deglaciation phases and has been dated using 10 Be to 15.4-12.0 ka (Rinterknecht et al, 2006) and 14.5-13.8 ka (Kalm et al, 2011), respectively. A single OSL date from the top of the Silezers dune yielded an age of 11.8 ± 2.4 ka (Nartišs et al, 2009).…”

“…At the proximal and distal slopes of these heights, locally the thickness of the Quaternary reaches 75 m. This characteristic of the sediment distribution refers to the strong glacial erosion on the tops of the bedrock-cored elevations, while at their proximal and distal slopes, sediments were preserved from the erosion of successive glaciations or were more easily trapped and released from the glacier. South-east of that zone, on the 'thick drift area' of Kleman et al (2008), the areas of bedrock elevation have very thick (.100 m) Quaternary cover, consisting of 5 -7 till layers and related glacial deposits (Guobyte & Satkūnas, 2011;Isachenkov, 1988;Kalm, Raukas, Rattas, & Lasberg, 2011;Raukas, 1978;Zelčs, Markots, Nartišs, & Saks, 2011). However, between these bedrock-cored elevations, which are called insular accumulative heights (Aboltinš et al, 1989), are lowland areas with much thinner (normally ,20 m) Quaternary sequences.…”

A thickness map of Quaternary deposits in the south-eastern sector of the last Scandinavian Ice Sheet (SIS) and in areas of Middle Pleistocene Moscow (Warthe) and the Dniepr (Drente) stages of the Late Saalian glaciation on the East European Plain is presented (Main Map). The map of the thickness and related statistics of the Quaternary deposits were calculated from the difference between the current digital terrain model and the bedrock surface topography model. The distribution of Quaternary deposits shows that 29% of the mapped territory has sediments less than 25 m thick, 16% more than 100 m and 1.2% more than 200 m. Within the SIS area, the thickness of sediments in the southern sector exceeds threefold the sediment thickness in the eastern flank. This difference is attributed to the bedrock depression in the south-east of the Baltic Syneclise rather than to glacial dynamics. The calculated average thickness of the sediments within the SIS area is ca 50 m, in the formerly glaciated area outside the LGM it is ca 61 m and outside the glaciated area ca 14 m. Our study confirms that, in formerly glaciated areas, the spatial distribution of sediments did amplify the differences in glacial bed topography with the exception of the southern and eastern flanks of the Moscow glaciation area where exceptionally thick Quaternary deposits have inverted bedrock depressions into elevated areas in recent terrain. We suggest that the map presented improves existing knowledge of this area by adding detail and thus contributing to the on-going development of numerical ice-sheet models.

Newly obtained pollen and diatom data from the Kamyshovoe Lake (previous Dobauen, Germ.), Vishtynets Highland, Baltic Uplands, analyzed by radiocarbon dating allowed to reconstruct the history of local vegetation during late Pleistocene and early Holocene. Pollen records show the formation of birchpredominating forest at ca. 13.4 ka cal. BP and the flourishing of pine towards the second half of the Allerød since about 13.2 ka cal. BP. The transition to the Younger Dryas around 12.7 ka cal. BP led to the development of sparse shrub tundra with Juniperus and communities of steppe herbs. Amelioration of the environmental regime enabled birch and pine woods to spread during the second part of the GS-1 event and the Preboreal. The late Preboreal time is marked by the appearance of Populus and an increase in the role of grasses in the vegetation cover, which can be correlated with similar open vegetation phases deduced from other pollen records in Europe (11.3-11.1 ka cal. BP). During the Boreal (since ca. 10.0 ka cal. BP) Corylus had its maximum value, Alnus, Tilia and Quercus appeared and spread while the birch-pine forests retreated.
