While there are no written records of eruptions in recent history, Eskimo elders have an account of the mountains smoking in the region. The oldest Eskimo settlements in Western Alaska date to around 200-500 BC, so mountains in the St. Michael volcanic field likely erupted sometime within the last 3,000 years.[2]
