Muksu
The Muksu cuts westward through the mountains of the northwestern Pamirs. It forms where the Seldara, which drains the great Fedchenko Glacier, meets the Sauksay, and it joins the Kyzyl-Suu below the Alay Valley. Their combined waters flow onward as the Surkhob, a headstream of the Vakhsh and ultimately the Amu Darya. The river's narrow, rugged basin lies among some of the highest and most heavily glaciated ranges of the Pamirs.
