Southern Yatsugatake Volcanic Group ( 南八ヶ岳 , Minami-Yatsugatake ) , also known as just Yatsugatake is a volcanic group of inactive volcanoes located on the border of Nagano Prefecture and Yamanashi Prefecture on Honshū in Japan .
11-645: The Southern Yatsugatake Volcanic Group is part of the Yatsugatake Mountains . The southern group is defined as the mountains south of the Natsuzawa Pass . The highest peak of the mountains is Mount Aka and the elevation is 2,899 metres. The southern Yatugatake mountains are steep and have alpine characteristics. The mountains of the Northern Yatsugatake Volcanic Group are gentler and lower. Mount Tateshina
22-406: A fast rate to 25–30 m tall. The crown is narrowly conical with horizontal branches and pubescent shoots. The shoots are pubescent, with short brown hairs. The leaves are needle-like and flattened, 1–3 cm long and 2 mm broad. They are glossy dark green above with two conspicuous bluish white stomatal bands underneath, and the tips are notched. The foliage is dense and points forward along
33-681: A rare form of spruce, Picea koyamae . Rock Ptarmigan ( Lagopus muta ) are also native to these mountains, but are under threat due to loss of the Siberian dwarf pine habitat and also due to expansion of the range of the red fox . Humans have enabled the expansion of the red fox by leaving trash behind in the mountains. Also growing in the subalpine zone are Abies veitchii and Abies mariesii . 35°58′15″N 138°22′12″E / 35.9708°N 138.3700°E / 35.9708; 138.3700 Abies veitchii Abies veitchii , also known as Veitch's fir or Veitch's silver-fir ,
44-468: A volcanic mountain range on the border between Nagano Prefecture and Yamanashi Prefecture on the island of Honshū in Japan . The mountain range consists of two volcanic groups, Northern Yatsugatake Volcanic Group and Southern Yatsugatake Volcanic Group . The two volcanic groups of Yatsugatake, North and South, have different characteristics. The North Yatsugatake mountains are gradual and lower while
55-417: Is a species of fir native to Japan from the islands of Honshū and Shikoku . It lives in moist soils in cool wet mountain forests at elevations of 1500–2800 m. It is very shade-tolerant when young, but is not long-lived. The name is derived from John Gould Veitch , who saw the common species on Mount Fuji in 1860 and identified it for European botanists. It is a coniferous evergreen tree growing at
66-662: Is also part of the Northern Yatsugatake mountains, but is listed separately. This volcanic group is listed among the 100 famous mountains in Japan . There the mountains are listed as Yatsugatake . These mountains are part of the Yatsugatake-Chūshin Kōgen Quasi-National Park . The volcanoes are stratovolcanoes that are 1 million to 200,000 years old. The rock is mainly basalt and andesite . The following major peaks make up part of
77-584: The South Yatsugatake mountains are steep and are more alpine in nature. The southern group ranges from the Natsuzawa Pass to the end of the mountain range. The northern range includes Mount Yoko to the other end of the range. Mount Tateshina is also included. These mountains form a major part of the Yatsugatake-Chūshin Kōgen Quasi-National Park . These mountains consist of older eroded complex volcanoes , which were made by repeated volcanic eruptions over many thousands years. The last eruption
88-637: The Southern Yatsugatake Volcanic Group and are listed by height: From the south, to Natuzawa Pass, beyond which the Northern Yatsugatake Mountains begin, the peaks are: From Natsuzawa Pass, it is possible to descend to Sakuradaira, via O-ren Hut and Natsuzawa Kosen, or directly to Honzawa Onsen, or continue through the Northern Yatsugatake Mountains. Yatsugatake Mountains The Yatsugatake Mountains ( 八ヶ岳連峰 , Yatsugatake-renpō ) are
99-418: The collection of peaks that exists today. Paul Hunt muses that this might not be far from the truth considering that Yatsugatake is older than Fuji and as Fuji rose in prominence Yatsugatake wore away. Deciduous forests reach up 800-1700m above sea level. Above this zone is the subalpine zone reaching up to 2500m. Siberian dwarf pine inhabits this subalpine zone. On one part of Mount Nishi under 1700m grows
110-408: The shoot, with the inner leaves being shorter and more erect than the lower leaves. The cone is purple-brown, cylindrical, 4–7 cm long and tapers slightly. The cones are upright and have slightly exserted and reflexed yellow-green bracts . The bark is smooth and light grey, and has resin blisters characteristic of many firs. There are two varieties : The wood is sturdy and elastic , and
121-495: Was estimated from 600 to 800 years ago at Mount Yoko of North Yatsugatake Mountains. This is the only remaining active volcano. The other volcanoes are extinct. The volcanoes consist mostly of pyroxene andesite. Yatsugatake also lies nearby to the Fossa Magna ( ja ). According to legend, Yatsugatake was once higher than Mount Fuji , but Konohanasakuya-hime , the goddess of Mount Fuji, tore it down out of jealousy, leaving
