Mount Shishaldin, Active stratovolcano on Unimak Island, Alaska.
Mount Shishaldin rises 2,857 meters above sea level, featuring a symmetrical cone shape with a base extending 16 kilometers in diameter.
The volcanic structure has developed over the past 10,000 years, built upon eroded remnants of an older volcano from the late Tertiary period.
The Aleut people named this mountain Sisquk, meaning the mountain that shows directions to travelers who lose their way.
The Alaska Volcano Observatory maintains continuous seismic monitoring of Mount Shishaldin through remote sensing technology and ground-based instruments.
The summit crater produces a constant steam plume while the upper 2,000 meters remain covered in permanent snow and ice throughout the year.
