Chuainisin

Chuainisin, known to the Haush as Jaius, is the island east of Tierra del Fuego later called Isla de los Estados. Its mountainous coast is deeply cut by bays and fjords, and its position faces the turbulent waters beyond the eastern end of the Beagle Channel. The Yagán name recalls the Indigenous maritime world that extended across the channels and islands of the far south.
