Yushan

Yushan

Yushan (Chinese: 玉山; pinyin: Yùshān; ‘Jade Mountain’ being the literal translation; it can also be referred to as Mount Yu) is the highest mountain in Taiwan and the fourth highest mountain on an island. In the past, Yushan was known among English-speaking expats and missionaries as Mt. Morrison, thought to have been named in honor of the 19th century missionary Robert Morrison. (More about this in the History section.) Today, the mountain is referred to as Yushan or Jade Mountain.

In the winter, Yushan is often capped with thick snow which makes the entire peak shine like stainless jade, hence its name. 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 Volcanos” category on the list of first round voting of the 77 nominees ended on July 7, 2009.

Yushan and surrounding mountains belong to Yushan Range, which is part of Yushan National Park in Taiwan. Yushan 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.

The highest point of Yushan range, Yushan, is 3,952 metres (12,966 ft) above sea level. Yushan was once in the ocean and raised to the current height because the Eurasian Plate slid under the neighboring Philippine Sea Plate.

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 metres (13,100 ft) about 50 kilometres (30 mi) from the coast. From this perspective, Yushan is even more magnificent if you consider it rises 8,000 metres (26,200 ft) steeply from the nearby ocean floor in such a short distance — est 100 kilometres (60 mi).

Geography and geology

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 small island (38th in the world).

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 (Traditional Chinese: 雲海, Pinyin: yúnhǎi) 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 often combine a trip to Yushan along with trips to Gunung Kinabalu and Fuji to form an "Asian Trilogy" hiking experience.

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

    * Yuhshan Main Peak (玉山主峰), 3,952 m (12,966 ft)

    * Yuhshan Eastern Peak (玉山東峰), 3,869 m (12,694 ft) — 4.5 kilometres (2.8 mi) from Main Peak

    * Yuhshan Northern Peak (玉山北峰), 3,858 m (12,657 ft) — 3.5 kilometres (2.2 mi) from Wind Tunnel (風口)

    * Yuhshan Southern Peak (玉山南峰), 3,844 m (12,612 ft) — 3.1 kilometres (1.9 mi) from Paiyun Lodge (排雲山莊)

    * Yuhshan Western Peak (玉山西峰), 3,467 m (11,375 ft) — 4 kilometres (2.5 mi) from Paiyun Lodge (排雲山莊)

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.

History

Jade Mountain was first observed by westerners in 1857. W. Morrison, captain of the American freighter SS Alexander, sighted this mountain while departing from Anping Harbor, in what is now Anping, Tainan. He recorded this sighting in his naval log, and the mountain gained the name Mount Morrison in western literature.

In 1900, after the annexation of Taiwan by the Japanese, two Japanese anthropologists, Torii Ryūzō and Mori Ushinosuke, became the first people to have been recorded ascending the mountain. They gave the mountain the name Niitakayama (新高山) or Mount Niitaka, literally the "New High Mountain", because it was even higher than Mount Fuji in Japan (was Empire of Japan) by 176 metres (577 ft). In 1937, Niitakayama was designated part of the Niitaka (New Highest) Arisan National Park (新高阿里山国立公園).

Under its Japanese name, the mountain was used as the secret code to signal the carrier fleet of the Imperial Japanese Navy to begin its attack against Pearl Harbor. The code was Niitakayama Nobore (literally "Climb the New High Mountain").

In 1966 a large bronze statue of Yu Youren was placed at the summit. The statue remained there until 1996 when it was cut down and thrown into a ravine by Taiwan independence activists.

In recent years, Yushan has played an important role in a new focus on Taiwan's identity. Because its iconic status, Yushan has been chosen to be the background of the newly issued NT $1,000 dollar bills on 20 July 2005.[6] Similarly, a newly found asteroid by Lulin Observatory of National Central University was named after Yushan on December 28, 2007.

Climate

Based on the data shown on Central Weather Bureau of Taiwan,[8] the figure on the right shows the monthly mean precipitation (unit: mm) of Yushan from 1971 to 2000.

Average annual rainfall in the Yushan area is about 3,600mm. 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. Overall speaking, winters are dry and summers wet in Yushan.

From September to April, the Yushan area is often covered with frost. However, due to strong wind, the frost level is not high, except in the valleys. At elevations above 2,000 meters, there is snow. At elevations of 3,000 meters or more, there are four consecutive months of snow accumulation. The first snow may appear in October and completely melts by May. Snow falls 24.3 days per year on average on Yushan, which is less than in the previous ten years. At lower elevations, snow may fall only 0.6 days per year. Snow mostly falls in January and February.
