One of only a few large west-flowing rivers in India, running in a rift between the Vindhya and Satpura ranges.

The Narmada flows west to the Arabian Sea along a down-faulted trough between the Vindhya and Satpura ranges, following the deep Son–Narmada lineament — one of the oldest and most persistent fracture lines in the Indian crust.

Because it runs in a structural rift rather than a self-cut valley, the river drops little and floods broad terraces — sediments that have yielded Deccan-era dinosaur eggs and one of India’s few archaic human fossils, at Hathnora.

A short reference note: this summary draws on third-party sources such as the Geological Survey of India and Wikipedia. In time I plan to give every geological feature its own learning-oriented write-up — with custom diagrams, graphs, and study pointers — as I’ve already done for the 11 locations that have an Instagram reel.
