Pumice Desert

Here a very thick layer of pumice and ash has created a dry area where the water permeates the ground too fast to sustain the vegetation.

Hole-in-the-Ground

Large, circular maar – a volcanic explosion crater. Its diameter is some 1,600 m, the floor is around 150 m below the surroundings but the rim around the crater – 35 to 65 m high. This maar formed some 13.5 – 18 thousand years ago.

Fort Rock

Unusual landmark – tufa ring that rises 105 m above the surrounding plain. The diameter of this formation is around 1,360 m.

S P Crater

Well-defined cinder cone with dark lava flow extending from it. This symmetric cone rises 250 m above surroundings.

Pu’u ‘Ō’ō

One of the cinder cones of Kīlauea, erupting continuously since January 1983. The longest-lived known rift-zone eruption. Continuous lava flows from this cone constantly change the geography of the island, here from time to time is observed also lava lake.

Molokini crater

Partially submerged volcanic crater. Some 600 m long crescent-shaped summit rises above the water. Exceptional scuba diving site due to calm water, good visibility, and exceptional biological diversity.

Mauna Kea

One of the highest mountains in the world if measured from its underwater base – 10,203 m high. It rises per 4,207 m above sea level. Due to dry and stable air above the volcano, it is one of the best places in the world for astronomical observation.

Mauna Loa

Volcano with the largest area in the world among the volcanoes that are above sea level. It rises 4 169 m above sea level and 9 170 m above its base.

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.
