Alay Range

The Alay or Alai Range (Алай тоо кыркасы; Алайский хребет) is a mountain range that extends from the Tien Shan mountain range in Kyrgyzstan west into Tajikistan. It is part of the Pamir-Alay mountain system. The range runs approximately east to west. Its highest summit is Pik Tandykul (пик Тандыкуль), reaching 5544 m. It forms the southern border of the Fergana Valley, and in the south it falls steeply to the Alay Valley. The southern slopes of the range drain into the Kyzylsuu or Vakhsh River, a tributary of the Amu Darya. The streams that drain the northern slopes of the range are tributaries of the Syr Darya, and empty into the Fergana Valley to the north of the range. Pik Skobeleva, 5051 m, is also a well-known summit. European route E007: Tashkent – Kokand – Andijan – Osh – Irkeshtam crosses the range by the Taldyk Pass. The range is also traversed by Pamir highway.

Some imprecise sources seem to use the term for the whole southern curve of the Tian Shan corresponding to the southern border of Kyrgyzstan, to up north until the perpendicular extension known as Fergana Range, but strictly speaking the Alay Mountains are strictly north of Alay Valley, while confusingly, Trans-Alay Range of Pamir Mountains lies to the south of that valley, as well as Turkestan Range and Zarafshan Range at far southwest. Pamir-Alay is collective term for many systems above, but not including any of the Pamirs.
