The Quechua-named hunting ground that hides a massive, iron-rich celestial secret
In short: Chaco, a province in northeastern Argentina, derives its name from the Quechua word for a hunting territory. Beyond its subtropical forests and alluvial plains, this region holds a rare historical legacy: the Campo del Cielo, a site where a massive shower of meteorites fell thousands of years ago.
The Gran Chaco, a vast lowland plain stretching across Argentina, Paraguay, and Bolivia, is a geosynclinal basin formed by the subsidence of land between the Andes and the Brazilian Highlands. This region is characterized by its alluvial nature, consisting of sandy and silty sediments that reach depths of up to 10,000 feet. The landscape is largely flat, with poor drainage that leads to extensive flooding during the rainy summer months, often inundating up to 42,000 square miles of the territory.
The name Chaco is rooted in the Quechua term for a hunting land or technique. Historically, large groups of hunters would gather to encircle prey, a practice described by Jesuit missioner Pedro Lozano in 1733. While the region is known for its subtropical climate and hardwood forests, it also contains the Campo del Cielo, or Heavenly Fields. This area, located on the border between Chaco and Santiago del Estero, is the site of a significant Holocene impact event that occurred four to five thousand years ago, leaving behind a protected field of iron meteorites.
Today, the province of Chaco faces distinct environmental and social challenges. It is often considered one of Argentina's poorest provinces, ranking last in both GDP per capita and the Human Development Index. Despite these hardships, the region maintains a rich cultural heritage, becoming the second province in Argentina to adopt indigenous languages—including Kom, Moqoit, and Wichí—as official languages in 2010. The interplay between its challenging geography, marked by extreme temperature contrasts and saline groundwater, and its enduring indigenous communities defines the modern character of this unique Argentine province.
