Oymyakon, Indigirka River, Sakha Republic, Russia

Etymology
It is named after the Oymyakon River, whose name comes from the Even word kheium 'unfrozen patch of water; place where fish spend the winter.' Though, by contraries, the dictionary of Tungusic languages says Even word heyum (hэjум) (kheium seems misspelling) is 'frozen lake.'
