Ethnohistoric and ethnographic accounts attest to the prominence of the Colca in regional trade networks both in terms of the size and capability of pastoralists in the upper Colca area to launch long-distance caravans, and for the draw created by the Colca valley agricultural sector on regional caravans. While archaeological evidence of passing camelid caravans is often subtle, in the course of survey work in 2003 a number of features were encountered that are potentially linked to caravan mobility.
