Mount Kaguyak is a stratovolcano located in the northeastern part of the Katmai National Park and Preserve in the U.S. state of Alaska. The 2.5km (01.6miles) wide caldera is filled by a more than 180 m deep crater lake. The surface of the crater lake lies about 550 m below the rim of the caldera. Postcaldera lava domes form a prominent peninsula in the center of the lake. The volcano is 901m (2,956feet) high and is topographically prominent because it rises from lowland areas near sea level in the south of the Big River.
Based on radiocarbon dating the caldera-forming eruption occurred about 5800 years before present. During this eruption at least 1200NaN0 were covered in a dacitic ignimbrite.
