The name quebrada literally "broken" translates as a deep valley or ravine. It receives its name from Humahuaca, a small city of 11,000 inhabitants. The Grande River RÃo Grande, which is dry in winter, flows copiously through the Quebrada in the summer.
The region has always been a crossroads for economic, social and cultural communication. It has been populated for 10,000 years, since the settlement of the first hunter-gatherers, which is evidenced by substantial prehistoric remains. It was a caravan road for the Inca Empire in the 15th century, then an important link between the Viceroyalty of the RÃo de la Plata and the Viceroyalty of Peru, as well as a stage for many battles of the Argentine War of Independence.
The quebrada has been placed on the UNESCO World Heritage List
