Yushan (mountain)

Yushan (Chinese: 玉山; pinyin: Yùshān; also known as Jade Mountain or Mount Yu) is the highest mountain in Taiwan and the fourth highest mountain on an island. Earlier, at the times when few Taiwanese could speak English, it was known among the expats, mostly missionaries, as Mt. Morrison, thought to have been named so in honor of the 19th century missionary Robert Morrison. After the Taiwanese have begun to assert themselves in the English language discourse on the island, the mountain has been referred to almost exclusively as Yu Shan.

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.^[1] 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).
