Location

edit

Geladaindong is located in the administrative unit known asTanggula Town: anexclave ofHaixi Prefecture, in the middle section of Tanggula Shan (the Tanggula Mountain Range).

The Geladaindong Peak is encircled by over twenty high peaks exceeding 6,000 meters (19,685 ft) in height. It is approximately 50 km (31 mi) long from north to south and approximately 20 km (12 mi) wide from west to east, covering an area of approximately 670 square kilometres (260 sq mi) with ice and snow, covered by over 40glaciers. This area is directly across the border fromAmdo County,Nagqu Prefecture,Tibet Autonomous Region.

TheQinghai-Tibet Railway crosses the Tanggula Mountain Range around 100 km (62 mi) to the east of Geladaindong Peak.

Climate

edit

Due to the area's arid climate, its annual precipitation is only 200 mm (7.9 in). In the high-altitude area of over 5,000 meters (16,404 ft), however, there exists violent local air circulation and its yearly precipitation is several hundred mm more than that in the foothill area. Thus,snow andhailstones frequently fall, presenting conditions for the development of glaciers. The average temperature is −5 °C (23 °F), and the hottest months are from June to August with a temperature of over 20 °C (68 °F), while the coldest month is January, with a temperature of −18 °C (−0.4 °F). In the high-altitude area of over 5,000 m (16,404 ft), it remains cold all year round, the lowest temperature being less than −30 °C (−22 °F).

Wildlife

edit

The mountain serves as a shelter for more than twenty kinds of wild animals, including thewhite-lipped deer, Asiaticwild ass,snow leopard, and alpinesnowcock.

Climbing

edit

Geladaindong was first climbed by Japanese team in 1985 after three years of trying to obtain a permit.^[3] They ascended the peak via the northwest ridge approaching from the northeast.

In 1997 an American team climbed a new route up the northeast face (55–60°).^[3] The team consisted of William N. Rom M.D., Dan Luchtel PhD, and Mark Newcomb. Mark Newcomb also pioneered a face solo route on the same expedition.

Although a dangerous peak to climb, Geladaindong is popular among Chinesemountain climbers. In 1994, the Mountaineering Association ofPeking University (MAPKU) became the first Chinese climbing team to reach the summit of Geladaindong.
