Asia, China, Qinghai-Tibet Plateau, Qiajajima I (5,930m), First Ascent
Qiajajima I (5,930m), first ascent. Qiajajima massif is the highest mountain in the headwaters of the Mekong River on the Qinghai-Tibet plateau. It is located at about N33° 28' and E95° 11' in the most isolated region of the Yushu Tibetan Autonomous Prefecture, Qinghai Province. The massif has two peaks, Qiajajima I (5,930m) and Qiajajima II (5,890m), which are indicated on the topographical map 1:100,000 of the China People’s Liberation Army. They remained unexplored because the region had long been closed to foreigners. In 1997 the first special permit was granted to a foreign party, the Niigata Mountaineering Association, for entering the unvisited area and attempting the untrodden peaks. The association sent an expedition and that year succeeded on Qiajajima II, but the highest peak, Qiajajima I, was not scaled due to unexpected frequent onsets of snow in spite of the summer season. In 2004 came another chance. I joined as deputy leader for an expedition to re-challenge Qiajajima I.
One microbus and two jeeps carried all the expedition members from Xining to Hot springs (336km), Yushu (510km) along the Qinghai-Sichuan Highway, then Zadoi (231km), Zaqeg-Zaigela campsite (76km) in five days from July 15 to 20. There we employed six muleteers and pack animals of 18 horses and eight yaks. On July 22 the caravan marched up 10km along the stream to a campsite at 4,444m. On July 23, heavy rainfall, strong wind and increase of river water made us stop. On July 24, we went up 10km along the main stream. A large landslide blocked the trail before it entered a gorge. We were forced to set up Base Camp there at 4,690m. On July 25, as it was not possible to take advantages of yaks and horses from BC, loads were ferried up by porters. The advance base camp (ABC) was built at 4,800m on the riverbank of the upper stream. The Chinese members and muleteers waited at BC until the climbing was over. On July 26 two members went ahead to pave the route. ABC-II was placed at 4,900m, and Cl was built at 5,140m, as ABC was too far away from the wall. Loads were carried to the higher camp. On July 27, C2 was set up at 5,360m at the foot of the wall.
On July 29 an advance party of three members commenced an assault on the summit. As there was no space to pitch a tent, they bivouacked at 5,587m. On July 30, they started climbing in the early morning. After ascending a chimney, they reached the main ridge, where they made a second bivouac at 5,780m. On July 31 the knife-edged main ridge became steeper. They detoured around the ridge to the north side and then reached the summit of Qiajajima I (5,930m) at 15:15. GPS indicated N33° 28' 33" and E95° 11' 33". The summiters were Shin-ichi Abe, Katsutoshi Suzuki, and Miho Kakinuma. On the way down they were again forced to bivouac, at about 5,600m on the wall, roped together. A fierce snowstorm bothered them all the night, dropping 20cm of snow. On August 11 everyone returned to Niigata via Xian.

JAN editor's notes: There are three outstanding mountain massifs in the source of the Mekong River. They form a watershed between the main stream of the Mekong River and a large tributary of the upper Yangtze River (Chinese name is Tongtian He). From east to west: 1) Qiajajima and neighboring peaks. 2) Sedari (5,770m) and 5,700m–5,800m peaks ranging to the west, where glaciers are most developed. This massif remains unvisited. No photographs of the mountains have been taken. 3) A massif at the true source of the Mekong River, where some 5,500m peaks were already climbed by a party of the Tokyo University of Agriculture, Japan, in 1994.
