8.1. Introduction

This chapter reviews the most significant findings of the Upper Colca Archaeological Research Project. The principal results will be summarized by time period, and then these larger findings of this research will be reviewed thematically by looking at the evidence with respect to specific issues such as quarrying, production, and modes of regional interaction. Subsequently this chapter will return to the four models for obsidian circulation in the Andes that were introduced earlier, in Section 3.7. This chapter concludes with a review of the theoretical implications of the research as well as a brief discussion of future directions in research at raw material sources in the Andes.
