Lithic artifacts manufactured in black obsidian from Pampa del Asador have a wide spatial and temporal distribution in Southern Patagonia. The distribution of this lithic resource was previously addressed to discuss mobility and circulation patterns of human groups in Patagonia. The aim of this work is to present new information regarding the distribution, density and size of obsidian pebbles and cobbles in Pampa del Asador. New outcrops are detailed and linked to regional archaeological information. The results shows that Pampa del Asador offers a wide-ranging availability and variability of pebbles and cobbles which are easily transportable for carrying out different technological strategies in the region. This will have implications when evaluating patterns of mobility, lithic production, manufacture of certain artifacts and chronology
