Narmada-Son trough

The Narmada-Son trough is a geological feature in central India that runs between the Vindhya and Satpura ranges. This trough is primarily defined by the courses of two major rivers: the Narmada River and the Son River. The Narmada flows westward, while the Son flows northeastward, making the valley a significant geographical feature. This region is largely forested and sparsely populated. The Vindhya Range, which forms the southern edge of the central upland of India, is considered to mark the border between northern and peninsular India.123
