There is no doubt that Patagonia is part of the Southern Cone but opinions deviate where it exactly starts and ends. The northern limit of Patagonia on the Chilean side can be seen as south as the Estuarió de Reloncaví (latitude 41° 30’ South) or as north as the river Río Biobío (about latitude 37° South if taking the mouth at Concepcion as reference). That’s a difference of about 500 km. On the Argentine side the understanding of the limits can be equally different. Some take the Río Negro with the tributary Río Limay as the northern limit (about latitude 39° South) others the Río Barrancas and the Río Colorado (Latitude 36° South). Also the southern limit is fuzzy. Some consider Tierra del Fuego as part of Patagonia others not.
