Omaguacas

The Omaguacas inhabited the valley of the Río Grande, a long passage through the mountains of the southern Andes. The Quebrada de Humahuaca connects the cold puna with the lower valleys, and people travelled its length for thousands of years. The Incas incorporated the route into their road network; under Spanish rule it carried traders and mule caravans between the Río de la Plata and the silver mines of Potosí.
