ORIA, Jimena  y  SALEMME, Mónica C. Visibilidad y preservación en Laguna Arturo, norte de Tierra del Fuego (Argentina): Un análisis geoarqueológico. Intersecciones antropol. [online]. 2016, vol.17, suppl.2, pp.89-100. ISSN 1850-373X.

The archaeological record in the surroundings of shallow lakes of the Fuegian steppe suggests that the human occupation has been recurrent in such space. Notwithstanding, the distribution of the evidence is highly variable and their findings are conditioned by different erosive processes acting upon the rocky and sedimentary materials in those environments. The examples of Laguna Arturo are presented here. Two sites are located in the higher sector of the southern coast; several isolated findings were spread along lower sectors of the coast, in small and incipient gullies excavated in aeolian deposits. Lithic artefacts are abundant; bones are less frequent and most of them are assigned to Lama guanicoe. Bones show different degree of preservation and few cultural marks. The lithic study included raw material identification, presence/absence of cortex, and size and weight of each piece. The record is analyzed from a distributional perspective and a sectoring for the lake environment is proposed. The geomorphological analysis of the settings added to several proxies (diatoms, ostracods, phytoliths) and an even incomplete radiocarbon sequence indicate environmental variability along the Holocene, which would have had influence on the human decisions to use this lacustrine area.
