This chapter sets out the geomorphological history of the basins of the lower Ica Valley — those processes of erosion and deposition which have formed and destroyed their archaeological record, and indeed given rise to today's landscape there. It reviews the results and interpretations of the geomorphological survey, which included: the definition of the basic geomorphic units across the lower Ica Valley; investigating the character of the relict river terraces of H-13 and G-8/9, which underlie most of their archaeology; understanding the extent of landscape and ecological change across the Samaca and Ullujaya basins, as revealed by buried ancient land surfaces; and evaluating those contexts from which archaeological and archaeobotanical data were extracted and subsequently analysed.
