The mountain range was mostly unexplored and unsettled, and only a single pass, Yarlhang La, opened through it.
The frozen peaks of this range, most notably the Mahamsaratsu Shan, reached high into the sky. Most reached elevations between 17,000 - 24,000 ft. (5200 - 7300m). Lakes from glacial run-off formed at the base of the mountains as melting snow and ice was trapped by rocky depressions. Flash flooding was a known danger in the region.
