チュクチ半島
At the beginning of the 20th century, speakers of the Sirenik Eskimo language inhabited the settlements of Sirenik, Imtuk, and some small villages stretching to the west from Sirenik along south-eastern coasts of the Chukchi Peninsula. As early as in 1895, Imtuk was already a settlement with mixed population of Sirenik Eskimos and Ungazigmit (the latter belonging to Siberian Yupik).
