Bahia Wulaia

Bahia Wulaia is a bay on the western shore of Isla Navarino along the Murray Channel in extreme southern Chile. The island and adjacent strait are part of the commune of Cabo de Hornos in the Antártica Chilena Province, which is part of the Magallanes and Antartica Chilena Region.

An archaeological site at Bahia Wulaia has been associated with the Megalithic seasonal settlements there of the Yaghan peoples about 10,000 years ago. Known as the Wulaia Bay Dome Middens, the site revealed that the people created fish traps in the small inlets of the bay. The stonework for those traps has survived, according to C. Michael Hogan, and was used by Yahgan into the 19th century.

In November 1859 a settlement known as Wulaia was the site of a Yahgan massacre of all but one of the crew and captain of the Allen Gardiner, a ship used by the South American Missionary Society. There had been a misunderstanding and cultural conflict between the parties.

The Yahgan are believed to have migrated to the main island of Tierra del Fuego from the north by a land bridge available more than 12,000 years ago, which disappeared after the end of an Ice Age. From there they easily navigated by canoe to Navarino Island and other islands. They are the "most southernmost aboriginal people in the history of the world." They created settlements in the coastal terraces on Navarino, building circular huts in the middle of ring middens. As they moved on a seasonal basis, numerous archeological sites of this period have been found on the island. They lived largely by taking fish and shellfish from the waters.
