About Isanotski Peaks
Isanotski Peaks is a stratovolcano rising to 2,446 meters (8,025 feet) in United States's North America Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Isanotski Peaks is located in United States, within the Aleutian Ridge Volcanic Arc of the broader North America Volcanic Regions. Situated at 54.77° N, 163.72° W in the Northern Hemisphere, the volcano lies within a temperate climate zone. At 2,446 meters above sea level, Isanotski Peaks rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
Rugged pinnacles form the summit of the deeply eroded Isanotski Peaks stratovolcano, locally known as Ragged Jack, at the center of a group of three volcanoes on eastern Unimak Island. Four poorly documented eruptions were noted in the 18th and 19th centuries. However, Miller et al. (1998) considered that some or all of these events could have been from neighboring Shishaldin, and that the extreme degree of erosional dissection makes recent eruptions unlikely.

How high is Isanotski Peaks?+
Isanotski Peaks has a summit elevation of 2,446 meters (8,025 feet) above sea level. At 2,446 meters, it is comparable in height to many significant mountain peaks and stands well above the tree line.
What type of volcano is Isanotski Peaks?+
Isanotski Peaks is classified as a Stratovolcano. Stratovolcanoes (also called composite volcanoes) are steep, conical volcanoes built up by many layers of hardened lava, tephra, and volcanic ash. They are among the most common and dangerous types, known for explosive eruptions.
Where is Isanotski Peaks located?+
Isanotski Peaks is located in United States, in the North America Volcanic Regions. More specifically, it lies within the Aleutian Ridge Volcanic Arc. Its exact coordinates are 54.765° latitude, -163.723° longitude.
Is it safe to visit Isanotski Peaks?+
Isanotski Peaks can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. United States may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
