Overview
- Researchers report numerical grouping patterns across the 1.5‑kilometer feature of roughly 5,200 pits, echoing the logic of Inka khipu record systems.
- Sediment analysis identified maize and plants used for basketry, evidence the team interprets as consistent with handling and tallying of goods.
- The site lies between two Inka administrative centers near a junction of pre-Hispanic trade routes at the transition from highland to coast.
- Authors propose an origin in the Chincha period as a marketplace with later Inka reuse for counting tribute after conquest.
- The interpretation remains provisional as earlier hypotheses persist in the debate and further corroboration is sought.
