Palaeoenvironmental conditions for human settlement at the Fuegian steppe (Argentina) based on diatom analysis. Lake Arturo as a case study

This paper adds information on the palaeoenvironmental evolution in northern Tierra del Fuego, using subfossil diatom analysis. The archaeological evidence suggested the presence of hunter-gatherer groups during the Holocene at the Fuegian steppe. Some shallow lake basins have denser archaeological...

description	This paper adds information on the palaeoenvironmental evolution in northern Tierra del Fuego, using subfossil diatom analysis. The archaeological evidence suggested the presence of hunter-gatherer groups during the Holocene at the Fuegian steppe. Some shallow lake basins have denser archaeological record than others; thus, it is interesting to evaluate and discuss if that might be related to different environmental conditions in the past. Lake Arturo offered opportunities for wildlife (guanacos and birds), and then, strategic meeting points for humans. A sediment core was taken from the lake with a Livingstone gravity corer. Diatom results suggest a brackish and shallow lake at Lake Arturo almost along the entire Holocene. The lacustrine basin started to desiccate during Middle Holocene or it had, at least, a similar configuration and dynamics as it has today.
