Sirenik409 km away
A highly divergent Eskaleut language of the village of Sireniki on the southern Chukchi peninsula, mutually unintelligible with its nearest Yupik relatives and sometimes treated as a third Eskimo branch. Died with its last speaker in 1997; the community now speaks Central Siberian Yupik and Russian.
Koryak1,106 km away
A Chukotko-Kamchatkan language of the Kamchatka peninsula. Spoken by Koryak reindeer herders and coastal communities; sister language to Chukchi within the Chukotian sub-branch.
Central Alaskan Yupʼik1,136 km away
The largest Yupʼik language, spoken across south-western Alaska. A sister language to Inuktitut within the Eskaleut family, with around 10,000 speakers.
Itelmen1,375 km away
The sole surviving language of the Kamchatkan branch of Chukotko-Kamchatkan, spoken in villages along the western coast of Kamchatka such as Kovran. Only a few elderly fluent speakers remain; known for extremely complex consonant clusters, and structurally so divergent from Chukchi-Koryak that its place in the family is debated.
Eyak1,948 km away
The sole non-Athabaskan member of the Athabaskan-Eyak branch of Na-Dené, spoken around the Copper River delta near Cordova, Alaska. Died with Marie Smith Jones in 2008; thoroughly documented by Michael Krauss, whose materials now support a second-language revival.
Inuvialuktun2,136 km away
The Inuit language of the Inuvialuit communities of the western Canadian Arctic. Smaller than Inuktitut and historically split between three sub-varieties: Sallirmiutun, Uummarmiutun, and Kangiryuarmiutun.
