St. Michael volcanic field

The St. Michael volcanic field in western Alaska, within the Bering Sea Volcanic Province, spans St. Michael and Stuart Islands as a complex landscape of 55 cones and craters rather than a single volcano. It includes low, broad shield volcanoes and maars created by explosive interaction between magma and water. Named features include Crater Mountain, The Sisters, St. Michael Mountain, Stephens Hill, Stuart Hill, and West Hill. No written record documents historical eruptions there, but oral traditions from Eskimo elders recall mountains smoking in the area, suggesting volcanic activity may have occurred sometime within the last 3,000 years.
