Etymology

The first Europeans who came to explore the southern tip of South America saw the campfires of the native inhabitants of the area (the Yaghan people, also called Yámana). The Spanish explorers hence named the area "Tierra del Fuego", meaning "land of fire".

Geography

Tierra del Fuego National Park is studded with mountains, lakes and rivers which form deep valleys. It is bounded on the west by the Chilean border, on the north by Lago Fagnano, and on the south by the Beagle Channel, which forms the shoreline. It encompasses an area of 63000 hectares (155,676.3 acre) and represents two ecoregions: the Altos Andes and the Patagonian Forest. While the former ecoregion is made up of hill ranges and slopes, the latter has high and jagged mountains, glacier valleys and semi-deciduous forests. The landscape of the park is the result of glacial erosion, which has created bays and beaches against a backdrop of rugged mountains and valleys.

Climate

The park experiences a temperate climate with frequent rain, fog and strong winds. Westerly winds over the sea maintain a uniform climate in the park. The average annual rainfall is 700 mm (27.6 in). Peak rainfall (snowfall at higher elevations) occurs from March through May; there is no dry season. Average temperatures are about 0 °C (32 °F) in winter and 10 °C (50 °F) in the summer. At Ushuaia, the recorded mean annual temperature reported is 5.4 °C (41.7 °F) with maximum monthly mean of 14.2 °C (57.6 °F) and minimum of -2.4 C.

History

Humans inhabited Tierra del Fuego as far back as 10,000 years ago. The Yaghan people, living in the harsh environment, survived on the natural resources of the sea. They lived on its beaches and made voyages into the sea in canoes made of lenga beech, hunted sea lion

s and collected shellfish. They lived in huts made of tree branches and trunks and clothed themselves with leather made from sea lion pelts. They smeared their body with the fat and grease of these animals to waterproof their skins. Trouble for the Yaghan people began in 1880, when European missionaries entered the area. Settlers brought diseases such as syphilis

, causing a rapid and nearly complete extinction of the Yaghan people. The Yaghan tribe was reduced in number from about 3,000 people in 1880 to less than 100 by the 1990s. Many of them were killed by "shoot exercises" and deliberate poisoning to exploit the sea lions, the staple of the Yaghan diet.

 prospectors came to Ushuaia, following rumors of large gold fields which proved to be false. In later years, Argentinian President Roca established a penal colony in the region in 1902, on nearby Staten Island, which resulted in its development. Prisoners were the main work force and were employed to construct the city and exploit the forests of the now Tierra del Fuego National Park. The train lines were also built by the prisoners, covering an area of 25 km (15.5 mi), which started from the Maipú Monte Susana camp and ran through the park. The city is now an important tourist center as the departure point not only for the park but also for voyages to Antarctica.

The Boundary Treaty of 1881 was an attempted resolution of the territorial dispute between Argentina and Chile, and stipulated that the boundary between the two countries would run south from "Cape Espiritu Santo, on the northern shore of Tierre del Fuego till it touches the Beagle Channel". This division meant that Argentina would be entitled to the eastern portion while Chile would have the western part of the Tierre del Fuego. However, the Treaty did not clarify on the terminus of the Beagle channel which created many territorial and collateral issues such as navigation rights. This resulted in a dispute between the two countries, particularly on the small islands (Picton, Lennox and Nueva

 and Pleistocene era. The lake has a total drainage area of 3042 km² (1,174.5 sq mi) with basin elevation ranging from 27 m (88.6 ft) at the lake level to about 1000 m (3,280.8 ft).
The lake water spreads over an area of about 600 m² (717.6 sq yd), with an average width of 6 km (3.7 mi) (maximum width is 10 km (6.2 mi) over a length of 104 km (64.6 mi) long and the maximum recorded depth is 204 m (669.3 ft), with an average depth reported as 70 m (229.7 ft). Its water volume is 1000 km³ (239.9 cu mi).

End of the World Train

Following the establishment of a prison in Ushuaia, in late 1909 and early 1910 the railway line called the Southern Fuegian Railway or the End of the World Train was established as a narrow gauge steam railway, replacing an old wood track railway drawn by bullocks. The steam engine driven railway was built over a length of 25 km (15.5 mi) along the Maipu Avenue on the water front, followed the eastern slope of Mount Susana and branched through the middle of the Pipo River valley into the Tierra del Fuego National Park. The line made with Decauville tracks of 500 mm (19.7 in) gauge, connected the prison camp with the forestry camp. The primary purpose of the railway was as a freight line to serve the prison of Ushuaia, and hence was known as the "Prison Train," and was used specifically to transport prisoners to the camps and transport the logged timber from forests. The prison was closed in 1947, and the railway was finally closed in 1952, following the reduction in forest resources and an earthquake which damaged the tracks. It was only in 1994, 40 years after it had been closed as a Prison Train, that the train was revived, refurbished with modern amenities, to be used as a heritage train, and claimed to be the southernmost functioning railway in the world.

in 1995), another made in Argentina and three diesel locomotives serve on the line. The park can now be reached from the outskirts of Ushuaia from the Fin del Mundo station (8 km (5 mi) west of Ushuaia) by the heritage railway line and runs over 5 km (3.1 mi), covering the distance in about 50 minutes.
