Frosty Volcano, Stratovolcano in Alaska Peninsula, United States
Frosty Volcano is a stratovolcano on Alaska Peninsula rising to about 5,670 feet with two merged craters at its summit. The cone displays multiple layers of hardened lava and ash from different eruption phases.
The volcano began erupting from a single central vent and later shifted its activity to create the current two-crater formation. The last steam emissions were recorded in summer 2001.
The Alaska Volcano Observatory monitors Frosty Volcano along with other volcanoes in the region to ensure population safety and scientific understanding.
This volcano sits in a remote location near Cold Bay and requires careful planning to visit given its isolation. Expect harsh weather conditions and rugged terrain.
The surface of Frosty Volcano contains layers of basaltic lava flows and displays evidence of both explosive and effusive volcanic episodes.
