What is the main island of the Tierra del Fuego archipelago?
Answer
Isla Grande de Tierra del Fuego
The main island of the Tierra del Fuego archipelago is Isla Grande de Tierra del Fuego.
Often shortened to Isla Grande or simply called Tierra del Fuego, this island is the largest landmass in the archipelago. It covers about 48,100 square kilometres, making it considerably larger than the other islands south of the Strait of Magellan.
The island is politically divided: its western and larger portion belongs to Chile, while its eastern portion belongs to Argentina. The international boundary continues southward through the Beagle Channel region, and the island contains settlements such as Porvenir in Chile and Río Grande and Ushuaia in Argentina.
A common mix-up is treating “Tierra del Fuego” as only the main island. Technically, Tierra del Fuego can refer to the whole archipelago, while Isla Grande de Tierra del Fuego identifies the principal island specifically. Hoste, Navarino, and Dawson are separate, smaller islands.
