After having travelled along the Ala-Baital defile, and followed the course of the Uzbel-Su, the party reached the Uzbel Pass, which separates the basin of the Kara-Kul from that of the Sary-Kol and Tarun-Gol.[...]The late M. Fedchenko disputed the existence of a meridional range on the east side of the Pamir, saying that Hayward had simply taken the abrupt side of the Pamir for a transverse mountain-range. Captain Kostenko, on the other hand, was impressed with its grandeur. It lies about 53 miles from the Uzbel Pass, and beyond it lies Kashghar, 40 miles further.[...]Through lack of provisions, Captain Kostenko was unable to push on to the Sary-Kol and compelled to return by the Uzbel Pass and the little Chon-Su defile. On emerging from thence, one comes upon a point where three roads converge—one to Badakhshan, one to Kokand (over the Kizyl-Yart), and the other to Kash- ghar (over the Uzbel Pass). The main force of the Alai column was rejoined at Archa-bulak, at the southern base of the Alai range. The whole distance marched by Captain Kostenko’s force, from the mouth of the Kizyl-Yart defile to the Uzbel Pass, was 90 miles.
