The Mount Katmai - even Katmai - is a stratovolcano on the Alaska Peninsula in southwest Alaska in Katmai National Park area. It lies in the Alëutenkette and is therefore part of the ring of fire around the Pacific . The rim of the crater reaches a height of 2047 m . The volcano has a diameter of 10 km. In its center there is a 3–4.5 km wide caldera in which a 250 m deep crater lake has formed at an altitude of 1286 m . The Katmai is glaciated.
Historical eruptions of the Katmai are not known. However, 10 km away there was a violent volcanic eruption of Novarupta in June 1912 . As a result of this eruption, the lava chamber below the summit of Katmai collapsed. The caldera, which is still filled with water today, was created.
