Southern Ural - the south, the widest part of the Ural Mountains, stretches from the river Ufa (near the village of Lower Ufaley) to the Ural River. From the west and east of the Southern Ural is limited to the East European, West Siberian Plain and the steppes near Aral Sea and Caspian sea.
The highest peak - Mount Yamantau - 1640 m. Due to the wide abutting the foothills of the Southern Ural extends up to 250 km with an average width of the Ural Mountains from 40 to 150 km.
The length of the Southern Ural - 550 km.
The relief of the Southern Ural is more complex, with numerous valleys and parallel ridges directed south-west and meridionally. The range includes the Ilmensky Mountains separated from the main ridges by the Miass River. The maximum height is 1,640 m (5,380 ft) (Mount Yamantau) and the width reaches 250 km (160 mi). Other notable peaks lie along the Iremel mountain ridge (Bolshoy Iremel and Maly Iremel). The Southern Urals extend some 550 km (340 mi) up to the sharp westward bend of the Ural River and terminate in the wide Mughalzhar Hills.
