Bottom sediments from Lake Pervoe Starushechye, on the White Sea shore, near Korabelnaya Bay, Chupa Town, 500 m from an archaeological site, were analyzed. The aim of our studies was to determine the position of the sea shoreline, to correlate archaeological sites relative to it, to date ancient settlements, and to reconstruct the paleoclimatic conditions and habitats of ancient people. Spore and pollen, diatom, and radiocarbon (14C) analyses were done. New evidence for the time of retreat of the seashore, the isolation of Lake Pervoe Starushechye from it and the time of the possible invasion of the area by ancient people was obtained. People were shown to inhabit the area from 3970 ± 120 to 3250 ± 120 14С y.a., when the sea shoreline reached modern levels of 19–22 m. The lake was then a ~8 m deep White Sea bay, in which marine gyttja was deposited. These events are reflected in the stratigraphy of the sequence and supported by the results of diatom and spore and pollen analyses. About 3500 y.a., mean annual temperatures in North Karelia were 2°С and annual precipitation ~50 mm/year higher than modern values. Spruce and pine-spruce forests with aspen and alder patches grew on the shore. A favorable climate and exuberant vegetation attracted people. Therefore, it is at the Atlantic-Subboreal boundary that the archaeological sites located at the above altitudes could arise. The lake separated from the White Sea 3020 ± 90 14С y.a. Freshwater sapropel was deposited in the isolated lake, as indicated by the composition of diatom flora and spore and pollen spectra. The sea shoreline declined to 17–16 m. Light-coniferous pine lichen-green moss forests with light-loving oligotrophic grasses were spreading actively throughout the study area.

How early did steppe dwellers penetrate the forests? The authors compare and contrast settlement on the steppe, in the forest and on the steep sea coast of western Patagonia, finding that the steppe is occupied first, from 11400 calendar years BP. But around 2800 calendar years BP settlements enter the forest almost simultaneously for a brief period along the length of the Cisnes river valley. Within a few centuries the experiment appears to be abandoned, and the focus of prehistoric peoples returns to the steppe.

AbstractFreshwater lakes existed intermittently in the Salton Trough of southern California during the late Holocene. The lakes formed north of the subaerial Colorado River Delta whenever the Colorado River flowed west into the trough instead of south to the Gulf of California. Water filled the trough to a maximum altitude of 12 m. Stratigraphy, radiocarbon dates, and supplementary evidence document four lacustral intervals of Lake Cahuilla between A.D. 700 and 1580. Archaeological sites are associated with the 12-m shoreline and their occupation correlates with these lacustral intervals.

This paper reports on the lithological, micropaleontological, and chronometric data (radiocarbon dating) for one of the areas of the White Sea coast. The sedimentary sequences were studied in the current lake basins, which were separated from the large basin at different times. The basin was situated in the head of the current Onega Bay. On the basis of these data, the bottom sediments were stratified and the Late Pleistocene-Holocene paleogeographic settings were reconstructed for the southeastern part of Onega Bay.
