Geography

The Trans-Alay is located in the area where the Pamirs and the Tian Shan come together. This heavily glaciated range forms the border between the Gorno-Badakshan region in Tajikistan and the Osh Region, Kyrgyzstan, stretching eastwards until the border with China. The name was from the viewpoint of Russian explorers in the region: The Alay Range lies to the north of the Alay Valley, formed by the Kyzyl-Suu or upper Vakhsh River, one of the principal tributaries of the Amu Darya. The range on the far side of the valley, more distant from Russia and its outposts, became known as the Trans-Alay. The southern valley dividing the Trans-Alay from the Pamir proper is that of the river Muksu.^[1]

Peaks

The highest peak in the range is the 7134 m high Ibn Sina/Lenin Peak.^[2] The Kyzylart and Ters-Agar mountain passes geographically divide the range into three parts: the western —highest peak Sat Peak [de] (5,900 m), the central —with some of the highest summits, including Lenin Peak, Dzerzhinsky Peak [de] (6717 m), Oktyabrsy Peak [de] (6780 m), and Marshal Zhukov Peak (6842 m),^[3] and the eastern — highest peak Kurumdy I summit (6614 m).^[1]
