Yu Shan or Yushan, also known as Mount Jade, Jade Mountain, Tongku Saveq or Mount Niitaka during Japanese rule, is the highest mountain in Taiwan at Template:Convert<ref name="Surv.Rev.39(2007)21">Template:Cite journal</ref><ref name="Batteries10(2024)202">Template:Cite journal</ref> above sea level, giving Taiwan the 4th-highest maximum elevation of any island in the world. It is the highest point in the western Pacific region outside of the Kamchatka Peninsula. Yushan and its surrounding mountains belong to the Yushan Range. The area was once in the ocean; it rose to its current height because of the Eurasian Plate's movement over the Philippine Sea Plate. Yushan is ranked 40th by topographic isolation.
The mountains are now protected as the Yushan National Park. The national park is Taiwan's largest, highest, and least accessible national park. It contains the largest tract of wilderness remaining on the island.
NamesEdit
Yushan or Yu Shan is the pinyin romanization of the Chinese name Template:Nowrap It is also known as Template:Nowrap, Template:Nowrap, and Template:Nowrap, calques of the same name. The name derives from its appearance in the winter, when its thick snow cover is thought to make its peak look like stainless jade.<ref name=tit/> "Yushan" or Jade Mountain was also the name of a location in ancient Chinese mythology, a paradise said to be the home of the Queen Mother of the West.
During the Qing Dynasty, Yushan was known in Chinese as Mugangshan ("Wooded Mountain") from its surrounding forests.Template:Sfnp Other Chinese names included Batongguan, transcribing its native Tsou name "Patungkuonʉ"; Baiyushan ("White Jade Mountain"); and Xueshan ("Snowy Mountain").<ref name=tit>Template:Cite news</ref> It was previously known in English as Template:Nowrap<ref name="Handbook">Template:Harvp.</ref> a name sometimes mistakenly thought to honor the missionary Robert Morrison, but simply the name of an American captain who sighted it.Template:Sfnp
Other native names for the mountain include Saviah and Tongku Saveq (Bunun; the latter means "highest peak" or "sheltering peak"<ref>Template:Cite book</ref>), Tanungu'incu (Kanakanavu), and Kanasian (Paiwan).
During Japan's rule in Taiwan, the mountain became known as Template:Nowrap or Niitakayama ("New High Mountain") because new surveying showed that it was Template:Convert higher than Template:Nowrap in the Japanese archipelago.<ref name="Handbook"/>
Geography and geologyEdit
The island of Taiwan is situated at the intersection of two tectonic plates: the Eurasian Plate and the Philippine Sea Plate. Even as "recently" as the late Paleozoic (some 250 million years ago), the land here was still but a sedimentary seabed layered with silt and sand. As the two plates began pressing against each other, the land buckled, bent, and created the landscape – composed of 165 mountains higher than Template:Convert above sea level on a relatively small island (38th largest in the world).
Yushan is also notable in containing the highest point on the Tropic of Cancer and the only point on that circle of latitude where there is any evidence of Quaternary glaciation.<ref>Late Pleistocene to Early Holocene Glacial Landforms of Yushan Area, Taiwan</ref> As recently as seventeen thousand years ago, permanent ice caps existed throughout Taiwan's highest mountains and extended owing to the wet climate down to Template:Convert; whereas currently, the nearest glaciers to the Tropic of Cancer are in Mexico on the Iztaccíhuatl volcano.
The ocean waters off Taiwan's east coast are deep; in fact, submarine slopes plunge down to the Pacific Ocean at a grade of 1:10 and the ocean reaches a depth of more than Template:Convert about Template:Convert from the coast.<ref name="central_geo_survey">Central Geological Survey, MOEA.

HikingEdit
With panoramic views, overlapping mountains, and deep, plunging valleys, Yushan National Park is well known for its scenery, sunrises, sunsets, geological features, and views of the clouds from above. Sea of clouds often fill the valleys. Yushan itself is the focal point of the park.
Yushan is one of the favorites among Taiwanese mountain climbers. For international peak baggers, Yushan is ranked as the 4th World Island Highpoints and the 3rd Asian Island Highpoints.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Some hikers combine trips to Puncak Jaya (Template:Cvt) in Indonesia and Mount Kinabalu (Template:Cvt) in Malaysia to create an "Asian Trilogy".<ref name="asian_trilogy">Yushan</ref>
Yushan has five main peaks:
- Main Peak (玉山主峰), Template:Convert, the most popular of the peaks<ref >{{#invoke:citation/CS1|citation

The east, west, north, and south peaks surround the main summit. The east peak rises to a height of Template:Convert and is considered one of Taiwan's Ten Major Summits (十峻). The south peak is a sharp pinnacle of black shale. The relatively accessible west side of Yushan is covered with thick forests. The north peak is part of a long, gently-rising ridge; this peak consists of two high points that resemble a camel's humps. The North Peak is also home to Taiwan's highest permanently occupied building, the Yushan weather station, where visitors are sometimes welcomed.

Flora and faunaEdit
-PeterWen-6.jpg){kind=link}
Taiwan, with the tropic of Cancer across the center of the island, has a climate between tropical and subtropical. The average temperature is Template:Convert. Here low elevation areas support evergreen broadleaved forests. As elevation increases, evergreen broadleaved forests are gradually replaced by deciduous forests and coniferous forests. At mountain peaks with alpine conditions, only mosses, liverworts and occasionally grasses can be found on the ground.<ref name=foc>Flora of China</ref>
All of the above vegetation variations can be seen in the Yushan area from low foothills to high summits with an elevation difference of Template:Convert. Because of these wide climatic and vegetation variations, this environment nurtures the richest and most diversified wildlife in Taiwan. Preliminary investigations reveal that there are 130 species of birds, 28 species of mammals, 17 species of reptiles, 12 species of amphibians, and 186 species of butterflies in Yushan National Park. In fact, Yushan is nicknamed "the ark" by academics who see it as a repository of Taiwan's rare species. It is almost an encyclopedia of Taiwan's ecological systems, a geological museum and an important habitat of one-third of Taiwan's endemic species, such as:
- Formosan serow (台灣長鬃山羊)
- Reeves's muntjac (台灣山羌)
- Formosan black bear (台灣黑熊)
- Formosan blue magpie (台灣藍鵲)
- Formosan rock macaque (台灣獼猴)
- Hemimyzon taitungensis (台東間爬岩鰍) and Varicorhinus tamusuiensis (Oshima) – Two unique fish species living in the Lekuleku River area.
HistoryEdit
Under the Qing Dynasty, W. Morrison, captain of the American steam freighter Alexander, sighted the mountain while departing from Anping Harbor (present-day Anping, Tainan) in 1857. His log was the first western mention of the mountain, which took his name in European accounts.Template:Sfnp<ref name=zoe>Template:Citation.</ref> European mountaineers couldn't access the mountain at the time due to hostile relations of local aborigines to both Qing authorities and Europeans.
Under the Japanese, the anthropologists Torii Ryūzō and Ushinosuke Mori became the first people recorded to summit the mountain in 1900. They gave it the name Template:Nowrap which was used as the name of the Niitaka Arisan National Park Template:Nowrap in 1937. The Imperial Japanese Navy also used the mountain's name in its "Go" signalTemplate:MdashNIITAKAYAMANOBORE 1208 ({{#invoke:Lang|lang}} [Kanji: {{#invoke:Lang|lang}}]), meaning "Climb Mount Niitaka 1208"Template:Mdashto begin the surprise attack against the USN Pacific Fleet and its base at Pearl Harbor, Hawaii, on 7 December 1941 (8 December [1208] in Japanese calendar). Template:Efn<ref>Template:Cite book</ref>
The Yushan weather station on the north peak was finished in 1943.<ref name="Taipei Times" >{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Under the Republic of China, a large bronze statue of Yu Youren was placed on the Yushan summit in 1966. The statue was cut down and thrown into a ravine by activists for Taiwan independence in 1996.<ref>1.</ref>
In recent years, Yushan has played an important role in a new focus on Taiwan's identity. Because of its iconic status, Yushan has been chosen to be the background of the newly-issued NT$1,000 notes on 20 July 2005.<ref name="new_taiwan_dollar_bill">Bulletin Board of Central Bank of the Republic of China.</ref> Similarly, an asteroid discovered by National Central University's Lulin Observatory on 28 December 2007 was named "Yushan" in honor of the mountain.<ref name="yushan_asteroid">Yushan Asteroid.

ClimateEdit
Yushan has an alpine climate (Köppen ET/ETf). The tip of Yushan is usually covered with frost from November to March. Elevations above Template:Convert may sometimes see snow during the winter months, and there are four consecutive months of snow accumulation at places with elevations higher than Template:Convert. The first snow may appear in October and completely melts by May. Snow falls 24.3 days per year on average on Yushan, and the number is gradually decreasing. Yushan receives around Template:Convert of precipitation annually. It rains an average of 140 days per year, with the greatest frequency between May and August. From May until the first part of June is plum rain season or monsoon season. Taiwan's typhoon season roughly falls between July and September. The peak month is in August, which sees Template:Convert of precipitation on average, compared to Template:Convert in December, the driest month.
