One of the northern extensions of the Pamir-Alay system, the Turkestan Range stretches for a total length of 340 km from the Alay Mountains on the border of Kyrgyzstan with Tajikistan to the Samarkand oasis in Uzbekistan. It runs in the east-west direction, north of the Zeravshan Range, forming the southern boundary of the Ferghana Valley in Tajikistan and Golodnaya Steppe in Uzbekistan. The highest elevations are in the east, near the border with Kyrgyzstan.
