Siona

The Siona, or Gâ’tɨya pâín, inhabit the forest country along the Putumayo River in the upper Amazon. Their settlements stand among waterways that connect the eastern Andean foothills with the great rivers farther downstream. Franciscan missionaries entered the upper Putumayo during the colonial period, encountering communities whose histories and relationships to the river long preceded the arrival of European priests.

The later city of Nueva Loja lies here.
