According to Francis Younghusband, there are actually two passes, the eastern or 'Old' Mustagh Pass (alt. about 5,422 m.) and the so-called 'New' Mustagh Pass, about 16 km (9.9 mi) to the west (altitude variously given as 5,700 and 5,800 m.) The pass is on the watershed between the rivers which flow towards the Tarim Basin and those flowing to the Indian Ocean.[1]
The route has been impassible to caravans since at least the middle of the 19th century due to the movement of the glaciers on it and, by 1861, when Godwin-Austen did his survey of the region, it was only in use by a few Baltis living in Yarkand who crossed it to visit their families. Frederic Drew reported that there had been no crossings between Yarkand and Baltistan between 1863 and 1870.[3]
"The old Mustagh Pass to the east had been out of use for thirty or forty years, on account of the accumulation of ice upon it, in consequence of which a new pass had been sought for, and another one to the west had been found. This latter pass had been in partial use up to ten years ago. No European had, however, crossed either of them, but Colonel Godwin-Austen in 1862 came very near the summit of the new pass from the southern side, when he was obliged to turn back on account of bad weather."[4]
History
There was apparently more abundant fodder and fuel along the Yarkand River than on the approaches to the Karakoram Pass:
"Turdi Kol took me a few miles further down the river and showed me two other equally good camping-grounds, and he says that there is considerably more pasture in the lower part of this valley than in that of the Karakash River, where Shahidula is situated, and that in the old days the valley was populated and cultivated and merchants went to and fro by the Mustagh Pass to Baltistan."[5]
Francis Younghusband (1863-1942) was the first European known to cross the pass which he did with much difficulty in 1887 after a request from Colonel Mark Sever Bell (1843-1906), finally reaching the village of Askole in Baltistan.[6]
Apparently there have only been two recorded crossings of the pass since then, "by an Italian expedition of exploration in 1929, and a French ski expedition in 1986."[7]
