Trident Volcano

Trident Volcano is a stratovolcano in Katmai National Park composed of andesite that was built up through repeated eruptions over geological time. Its complex structure with multiple peaks creates a distinctive geological formation in the Alaskan landscape.

The volcano was named in 1916 by researcher Robert Fiske Griggs, who led a National Geographic expedition through the region. The name comes from the three prominent peaks visible from the volcano's face.

The volcano holds significance in the stories and knowledge systems of indigenous Athabascan and Yupik peoples who have lived in the region for generations. Their understanding of this landscape shapes how the area is perceived and respected by those who visit today.

The volcano is located in a remote national park and can typically be accessed only by plane or boat from nearby towns. Visitors should prepare for harsh weather conditions and the physical demands of traveling through undeveloped terrain.

A notable feature is the amphitheater formation on the volcano's southwest side, where a new dome grew from the ground over several decades in the middle of the 20th century. This dome represents a rare example of volcanic growth that scientists could directly observe in modern times.
