Kaimur Range
Kaimur Range (also spelt Kymore) (Hindi: कैमूर पहाड़ियाँ) is the eastern portion of the Vindhya Range, about 483 kilometres (300 mi) long, extending from around Katangi in Jabalpur district of Madhya Pradesh to around Sasaram in Rohtas district of Bihar. It passes through the Rewa and Mirzapur divisions. The range never rises more than a few hundred metres above the surrounding plains and has a maximum width of around 80 km.
The range
The southern part of the Vindhyan Range up to Katangi is called Bhander Range. Beyond this point the escarpment enclosing the land-locked valley of Sirampur and the hill range in continuation is called the Kaimur Range.
The most important physioraphic feature in eastern Madhya Pradesh is the great Kaimur escarpment. This forms the watershed or divide for two of the major rivers of peninsular India, the Son on the south and Tons on the north. Throughout its length of 300 miles and throughout its continuation into Narmada valley, it is not breached at any point by any stream flowing northwards, with a few minor exceptions. Everywhere the scarp rises to a height of 500 to 1000 feet above the low ground at its feet. The unique feature of the absence of any gorge or wind gap across the Kaimur scarp indicates that no stream of considerable size ever flowed due north across the scarp.
