Using an alternative method of lithic analysis, the mass aggregate analysis, we have been able distinguish differences in site functions for Archaic Period sites in the Andean Highlands. Systematic surface collections of lithic debris conducted at two sites in the Rio Ilave Drainage of Peru represent different patterns of site use. The detected variablity in our data for site function is crucial for understanding important changes in settlment patterns in the early prehistory of the Lake Titicaca basin. Results of this study are both substantive and methodological as this type of analysis has proven to be very useful in understanding Archaic period lithic scatters in the highlands. Furthermore, test excavations at one of the sites support the interpretations of the significance of the surface data.
