Чукотский полуостров
Some speakers of Siberian Yupik languages used to speak an Eskimo variant in the past, before they underwent a language shift. These former speakers of Sirenik Eskimo language inhabited the settlements of Sireniki, Imtuk, and some small villages stretching to the west from Sireniki along south-eastern coasts of Chukchi Peninsula. They lived in neighborhoods with Siberian Yupik and Chukchi peoples.
