Baranof Warm Springs

Group of nine warm springs with temperature up to 49 °C. Next to the springs is powerful waterfall – outlet of Baranof Lake.

Mount Shishaldin

The most symmetrical cone-shaped and glacier-clad mountain in the world. This 2857 m high volcano is continuously active and emits a plume of steam.

Mount Martin

Volcano with a very active fumarolic activity. The crater contains an intermittent acidic lake and thick sulfur deposits.

Mount Douglas crater lake

Approximately 160 m wide, highly acidic crater lake with pH of its water reaching 1.1.

Mount Cleveland

Near symmetrical stratovolcano, 1 730 m high. Almost constantly active. Nearby from the sea rise several more symmetrical volcanic cones – such as the beautiful cone of Mount Carlisle and Herbert Island.

Fumaroles of Mount Griggs

Hot and vigorously active fumaroles on the southwest flank of the volcano are roaring very loudly and can be heard far away.

Devil Mountain Lakes

Possibly the largest maar in the world – two joined round lakes formed by a volcanic eruption some 21 000 years ago. The diameter of lakes reaches 8 km. Several more maar lakes are nearby.

Table Rock SC

970 m tall mountain with a fairly flat surface and steep slopes of monolithic granite. This mountain is a batholith – fragment of magma that was pressed upwards during the Ordovician period some 430 million years ago.

Peachtree Rock

An unusual mushroom rock that stood on a narrow leg and resembled an overturned pyramid. It was some 6 m high. The rock fell in December 2013.

Raven Cliff Falls SC
