ABSTRACT
Starting from Aymara opposites concepts of marca (town) and pampa (unlimited space), this chapter attempts to specify the cultural value of the numerous material interventions in the road network of Tarapacá Desert, a territory called pampa and dominated by Aymara speakers. Precisely, the monumental rock art works known as geoglyphs offered a cultural solution that also enabled a particular identity to be assigned to the subjects involved in the trafficking of goods and ideas. We argue that this practice reduced the differences between the territorial and geographic origins of marine hunter-gatherers and those of oasis-based agropastoral groups who ventured into the desert.
