The Hakkōda Mountains or the Hakkōda Mountains ( Japanese 八甲田山 , Hakkōda-san ) is a volcanic mountain range in the prefecture of Aomori in the north of the Japanese main island of Honshū . The mountain range consists of more than a dozen stratovolcanoes and lava domes , which are divided into two groups. The northern group rises from the rim of a caldera eight kilometers in diameter that was formed in the Pleistocene . The southern group is older than this caldera.

description

The highest peak of the mountain range is the Ōdake ( 1584 m ), an ascent from Sukayu Onsen takes about four hours. The abundance of snow in the region makes the Hakkōda Mountains a popular destination for touring and downhill skiers . Around 150,000 tourists are counted here every year. There are two shelters that can be used for overnight stays on longer tours. The lower slopes are wooded with interspersed bog areas .

Together with Lake Towada and the Oirase River , the Hakkōda Mountains form the Towada-Hachimantai National Park .

The Hakkōda tunnel crosses part of the mountain range. At over 26 kilometers in length, it is one of the longest rail tunnels in the world.

geology

The volcanic peaks consist of mafic rocks, mainly andesite , dacite and basalt . Although the two different volcanic groups formed in the Pleistocene, the southern group is older than the northern. The rocks in the south are 700,000 to 1.7 million years old, those in the north only 13,000 to 700,000 years old.
