Circulation of Goods and Information in Southern Patagonia During the Late Holocene: An Integrated Analysis of Engravings and Black Obsidian Artefacts

This paper explores the strategies implemented by hunter-gatherer groups in Southern Patagonia during the Late Holocene in relation to the circulation of goods and information. Previous archaeological investigations have revealed important changes in human mobility and land-use patterns during this period, associated with increasingly dry environmental conditions. In this context, we undertake a broad spatial scale analysis of the circulation of goods and information through the integrated examination of two lines of evidence: rock art and lithic raw materials. Specifically, we consider the distribution of engravings and black obsidian artefacts assigned to the Late Holocene. The former can offer certain insights into the circulation of information, and the latter are indicative of the circulation of goods. Our analysis suggests that during this period different strategies were developed by hunter-gatherer groups to face the changing environment. Several implications concerning social interaction and the movement of people during this period in Southern Patagonia are discussed.
