Each year in June, the people of the comunidad campesina of Huinchiri, along with villagers from three other nearby communities, rebuild a suspension bridge across the canyon of the upper Río Apurimac. The bridge is a keshwa chaca made of ropes hand woven of qqoya grass, a type of Andean bunchgrass. The Quechua people continue to build the bridge annually, as apparently they have done since Inka times. It is their custom, and by maintaining the bridge they honor their ancestors and Pachamama.
While traveling through, Chile, Argentina, Bolivia en Peru in 2012 we found the Keshwa Chaca Inca bridge near Cusco, Peru.
