Kotumsar caves

Also known as Kotumsar, Kotamsar, Gopansar, Kanger Valley

A limestone cave nearly a kilometre and a half long in the Kanger valley of Bastar, cut by an underground stream through Kanger limestone, with stalactite and stalagmite chambers and pools deep in the dark zone. It is among the longest natural caves in India and one of very few with a described cave-adapted fauna.

Worth knowing

Its pools hold a blind cave fish, Nemacheilus evezardi, whose eyes are reduced and whose daily rhythm has been studied precisely because it lives without light. The cave floods every monsoon and is shut for months, and the local Bhatri name means simply the cave of Kotumsar — it was known to the surrounding villages long before it was surveyed in 1951.
