Tacshic

Tacshic is a name associated with eastern groups of the Qom, also known as Toba, in the Gran Chaco. Qom communities speak a Guaycuruan language and traditionally hunted, fished and gathered across woodland, grassland and riverine wetlands. They moved within extensive territories as water and food changed with the seasons. The eastern Chaco is crossed by rivers flowing toward the Paraguay and Paraná.

The later city of Formosa lies here.
