Yu Shan

Yu Shan or Yushan, also known as Mount Jade, Jade Mountain, or Mount Yu, and known as Mount Niitaka during Japanese rule, is the highest mountain on Taiwan at 3,952 m (12,966 ft) 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 surrounding mountains belong to 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.

This article is about the mountain in Taiwan. For the mythological mountain, see Jade Mountain (mythology). For other uses, see Yushan (disambiguation).

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 in Taiwan and is also valued for its pristine forests and faunal diversity, including many endemic species. On July 21, 2009, Yushan was elected one of 28 finalists in the New7Wonders of Nature voting campaign. It even had held the top position in the “Mountains and Volcanoes” category on the list of first round voting of the 77 nominees ended on July 7, 2009.

Names

Yushan or Yu Shan is the pinyin romanization of the Chinese name 玉山. It is also known as Mount Yu, Mount Jade, and Jade Mountain, 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.[1] "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.[2] Other Chinese names included Batongguan, transcribing its native Tsou name "Patungkuonʉ"; Baiyushan ("White Jade Mountain"); and Xueshan ("Snowy Mountain").[1] It was previously known in English as Mount Morrison,[3] a name sometimes mistakenly thought to honor the missionary Robert Morrison, but actually simply the name of an American captain who sighted it.[2]

Other native names for the mountain include Saviah and Tongku Saveq (Bunun; the latter means "highest peak"), Tanungu'incu (Kanakanavu), and Kanasian (Paiwan).

During Japan's rule in Taiwan, the mountain became known as Mount Niitaka or Niitakayama ("New High Mountain") because new surveying showed that it was 176 m (577 ft) higher than Mount Fuji in the Japanese Islands.[3]

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 – 165 mountains higher than 3,000 m (9,800 ft) 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.[4] 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 2,800 m (9,190 ft); 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 4,000 m (13,100 ft) about 50 km (30 mi) from the coast.[5]

Hiking

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. Indisputably, Yushan itself is the focal point of the park.

Yushan is one of the favorites among Taiwanese mountain climbers. International peak baggers Yushan is ranked as the 4th World Island Highpoints and the 3rd Asian Island Highpoints. After Puncak Jaya (4,884 m (16,024 ft)) in Indonesia and Mount Kinabalu (4,095 m (13,435 ft)) in Malaysia to form an "Asian Trilogy" hiking experience.[6][7]

Yushan has five main peaks with the Main Peak being the most popular:

  • Main Peak (玉山主峰), 3,952 m (12,966 ft)
  • Eastern Peak (玉山東峰), 3,869 m (12,694 ft) – 1.2 km (0.7 mi) from Main Peak
  • Northern Peak (玉山北峰), 3,858 m (12,657 ft) – 2.2 km (1.4 mi) from Wind Tunnel (風口)
  • Southern Peak (玉山南峰), 3,844 m (12,612 ft) – 3.1 km (1.9 mi) from Paiyun Lodge (排雲山莊)
  • Western Peak (玉山西峰), 3,467 m (11,375 ft) – 4 km (2.5 mi) from Paiyun Lodge (排雲山莊)

The east, west, north, and south peaks surround the main summit. The east peak rises to a height of 3,869 m (12,694 ft) 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 the occasional visitors are given a warm welcome.

Taiwan, with the tropic of Cancer across the center of the island, has a climate between tropical and subtropical. The average temperature is 23.5 °C (74.3 °F). 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.[8]

All of the above vegetation variations can be seen in the Yushan area from low foothills to high summits with an elevation difference of 3.6 km (2.2 mi). Because of this 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:

History

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.[2][9]

Under the Japanese, the anthropologists Torii Ryūzō and Ushinosuke Mori became the first people recorded to summit the mountain in 1900.

In 1900, during Japanese rule, two Japanese anthropologists, became the first people to have been recorded ascending the mountain. They gave it the name "Mount Niitaka", which was used as the name of the Niitaka Arisan National Park (新高阿里山国立公園) in 1937. The Imperial Japanese Navy also used the mountain's name in its signal—Niitakayama Nobore (ニイタカヤマノボレ) or "Climb Mount Niitaka"—to begin the surprise attack against the USN Pacific Fleet and its base at Pearl Harbor, Hawaii, on 7 December 1941.[10]

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.[11]

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.[12] Similarly, a newly-found asteroid by Lulin Observatory of National Central University was named after Yushan on 28 December 2007.[13]

Climate

Yushan has an alpine climate (Köppen ET). The tip of Yushan is usually covered with frost from November to March. Elevations above 2,000 metres (6,562 ft) may sometimes see snow during the winter months, and there are four consecutive months of snow accumulation at places with elevations higher than 3,000 metres (9,843 ft). 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 3,600 mm (141.7 in) of precipitation annually. It rains an average of 140 days per year, mostly 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 520 mm (20.5 in) of precipitation on average, compared to 70 mm (2.8 in) in December, the driest month.
