Abstract We present the results of the study of the use of obsidian in the lithic set of Cueva Nacimiento 1 in a late agropastoral context. The results indicate that obsidian was a resource used in a way that maximized it within a mixed technological strategy of conservation-expediency. At the same time, the comparison with the local raw materials allows to affirm that in spite of the local availability of good quality rocks, the frequency of obsidian in the set is predominant, and its use is destined to the manufacture of instruments of high and low energy investment. These results raise the possibility that the groups that used the cave in Late period moments could have been part of persistent interaction networks of wide scope. This relatively open access to materials from different sources could offer the possibility of a technological strategy that combined artifacts of conserved nature and other expeditious ones on raw materials of excellent quality.
