¿Cuántas zonas distinguen a la Patagonia?

The Colorado and Barrancas Rivers, which run from the Andes to the Atlantic, are commonly considered the northern limit of Argentine Patagonia.[1] The archipelago of Tierra del Fuego is sometimes included as part of Patagonia. Most geographers and historians locate the northern limit of Chilean Patagonia at Huincul Fault, in Araucanía Region.[2][3][4][5]
