mountains on the right bank of the Syr Darya River, near the southwestern extremity of the Kurama Range, near the city of Leninabad, Tadzhik SSR. Length, 35–40 km; elevations to 1,624 m (Mount Muzbek).
Mogoltau is composed mainly of Paleozoic granites and sedimentary metamorphic rock masses. The slopes are dissected by the short, deep valleys of ephemeral watercourses. Desert and semidesert topography predominates. Breaking through the spurs of Mogoltau (the Farkhad cliffs and the rocky Shirin-Kyz ridge) at its emergence from the Fergana Valley, the Syr Darya forms the Bekabad rapids, where the Farkhad Hydroelectric Power Plant has been constructed.
