The research on which this text is based has been financially supported by the Berne University Research Foundation (2009–2011) as well as by an Ambizione Research Fellowship of the Swiss National Science Foundation (2012–2014). During my stays in South Africa, the Departments of Anthropology at the University of the Witwatersrand, Johannesburg, and the University of South Africa (UNISA), Pretoria, provided me with welcoming and inspiring research environments. This article benefitted greatly from engaged discussions around its presentation at various occasions, notably our ECAS 2011 panel Transition and Justice: Negotiating the Terms of New Beginnings in Africa, held in Uppsala. I am particularly grateful to my co-convener and co-editor Gerhard Anders as well as Laurens Bakker, Keebet von Benda-Beckmann, Ben Cousins, Julia Eckert, Marion Fresia, Vinodh Jaichand, Steffen Jensen, Tim Kelsall, Hanri Mostert, Johanna Mugler, David O'Kane, Julia Pauli, Mats Utas, Julia Zenker and the anonymous referees of Development and Change for their critical engagements.

Samples from sediment cores collected during the Swedish Deep-Sea Expedition 1947-1948 have been analyzed in the Geochemical laboratory of the Geological Survey of Sweden. Most samples were placed at our disposal by Professor Hans Pettersson, leader of the expedition mentioned. For complementary studies, samples from the Atlantic and Indian oceans were included in our investigation and the samples placed at our disposal by Professor B. Kullenberg, Göteborg. From the Tyrrhenian Sea we got samples from Professor E. Norin, Uppsala.

The youngest ice marginal zone between the White Sea and the Ural mountains is the W-E trending belt of moraines called the Varsh-Indiga-Markhida-Harbei-Halmer-Sopkay, here called the Markhida line. Glacial elements show that it was deposited by the Kara Ice Sheet, and in the west, by the Barents Ice Sheet. The Markhida moraine overlies Eemian marine sediments, and is therefore of Weichselian age. Distal to the moraine are Eemian marine sediments and three Palaeolithic sites with many C-14 dates in the range 16-37 ka not covered by till, proving that it represents the maximum ice sheet extension during the Weichselian. The Late Weichselian ice limit of M. G. Grosswald is about 400 km (near the Urals more than 700 km) too far south. Shorelines of ice dammed Lake Komi, probably dammed by the ice sheet ending at the Markhida line, predate 37 ka. We conclude that the Markhida line is of Middle/Early Weichselian age, implying that no ice sheet reached this part of Northern Russia during the Late Weichselian. This age is supported by a series of C-14 and OSL dates inside the Markhida line all of >45 ka. Two moraine loops protrude south of the Markhida line; the Laya-Adzva and Rogavaya moraines. These moraines are covered by Lake Komi sediments, and many C-14 dates on mammoth bones inside the moraines are 26-37 ka. The morphology indicates that the moraines are of Weichselian age, but a Saalian age cannot be excluded. No post-glacial emerged marine shorelines are found along the Barents Sea coast north of the Markhida line.
