Quick Summary

The Son valley is a sparsely populated, largely forested region in central India. It is geologically an extension of the Narmada River valley and is bordered by the Kaimur Range to the north and the Chota Nagpur plateau to the south. The Son River, the principal southern tributary of the Ganges (Ganga) River, flows through this valley before joining the Ganges near Patna. The river's flow is seasonal, and it is not significant for navigation, though dams have been built on its tributaries.1
