Mount Redoubt

Mount Redoubt is an active stratovolcano in the Chigmit Mountains of the Aleutian Range in Alaska. Its summit reaches 10,197 ft (3,108 m), making it one of the higher peaks in the region.

The mountain is noted for its glaciated summit and explosive eruptions that produce high ash plumes and pyroclastic activity. Scientific monitoring, aerial observations, and occasional flyover viewing are the main ways people observe the volcano; public access near the summit is limited and weather can change rapidly.

Recorded eruptions in the modern era include major events in 1989-1990 and again in 2009, both of which produced significant ash clouds and local volcanic hazards. The Alaska Volcano Observatory maintains ongoing monitoring and issues alerts when activity increases.

Mount Redoubt sits on the northern side of Cook Inlet in south-central Alaska, within the Chigmit subrange of the Aleutian Range. It is located southwest of Anchorage and is visible from parts of the surrounding lowlands when weather permits.

• Volcanic activity: Eruptions are explosive and can send ash plumes high enough to disrupt aviation; the volcano is monitored by the Alaska Volcano Observatory.
• Summit elevation: Glaciated summit reaches 10,197 ft (3,108 m) above sea level, and eruptions have produced lahars and ashfall that affect nearby lowlands.
