1200-417: The main island between 1883 and 1909. Numerous Argentines, Chileans, and Croatians settled on the main island, leading to increased conflicts with native Selk'nam .

1280-452: The nineteenth century. Missionary Thomas Bridges (1842–1898) learned the native language and compiled a 30,000-word Yaghan grammar and dictionary while he worked at Ushuaia. It was published in the 20th century and is considered an important ethnological work. An 1879 Chilean expedition led by Ramón Serrano Montaner reported large amounts of placer gold in the streams and river beds of Tierra del Fuego. This prompted massive immigration to

While Mount Darwin had previously been thought to be the tallest mountain in the archipelago, this distinction now belongs to the unofficially named Monte Shipton at 2,580 metres (8,460 feet). The topography of Tierra del Fuego can be divided into four regions: an outer archipelago region ( Spanish : Región Archipielágica ) to the south and west, a mountainous region in the south ( Spanish : Región Cordillerana ),

1360-526: The only forests in the world to have developed in a climate with such cold summers. Tree cover extends very close to the southernmost tip of South America. Winds are so strong that trees in wind-exposed areas grow into twisted shapes, inspiring people to call them "flag-trees". Tree vegetation extends to the southern tip of the region, Isla Hornos , although the Wollaston Islands are mostly covered by subantarctic tundra except in wind sheltered areas where

1400-669: The region is made up of steppe and cool semi-desert. Six species of tree are found in Tierra del Fuego: canelo or winter's bark ( Drimys winteri ); Maytenus magellanica ; Pilgerodendron uviferum , the southernmost conifer in the world; and three kinds of southern beech : Nothofagus antarctica ; Nothofagus pumilio ; and the evergreen Nothofagus betuloides . Several kinds of fruit grow in open spaces in these forests, such as beach strawberry ( Fragaria chiloensis var. chiloensis forma chiloensis ) and calafate ( Berberis buxifolia ), which have long been gathered by both Native Americans and residents of European descent. They are

1440-521: The south. The earliest human settlement occurred approximately 8,000 BC. The Yaghan were some of the earliest known humans to settle in Tierra del Fuego.

The name Tierra del Fuego was given by the Portuguese explorer Ferdinand Magellan while sailing for the Spanish Crown in 1520; he

1480-449: The trees can survive. Forests from Tierra del Fuego have expanded beyond local importance. These forests have been a source of trees that have been transplanted abroad in places with similar climate, but which originally were devoid of trees, such as the Faroe Islands and nearby archipelagos. Most species were gathered from the coldest places in Tierra del Fuego, mainly sites with tundra borders. This effort resulted in positive changes, as

1520-610: The vessel. As a result, Zurubí was refurbished and re-commissioned in 1993. As of early 2016, Zurubí is in active service based still in Ushuaia.

1600-490: Was the first European to visit these lands. He believed he was seeing the many fires ( fuego in Spanish) of the indigenous inhabitants, which were visible from the sea, and that the "Indians" were waiting in the forests to ambush his armada . In 1525, Francisco de Hoces was the first to speculate that Tierra del Fuego was one or more islands rather than part of what was then called Terra Australis . Francis Drake in 1578 and
