Lithic artifacts manufactured in black obsidian from Pampa del Asador have a wide spatial distribution in Central Patagonia. Different geochemical analyzes have determined its distribution from Magellans Strait to Chubut province. The initial research in Pampa del Asador had determined the characteristics of this source. Subsequently, the presence of smaller pebbles to the east and southeast of the area was established.Also, the distribution of this lithic resource had been addressed to discuss mobility and circulation of human groups in Patagonia. The aim of this work is to display new information about the distribution, density and size of obsidian pebbles at Pampa del Asador. New outcrops are detailed and linked to regional archaeological information. With the information available, the focus is to discuss the role of Pampa del Asador in hunter-gatherers mobility and technology.
