Korappuzha River

Originating in the majestic mountains of Wayanad district of Kerala, Korappuzha also known as Elathur River is considered as the cordon sanitaire between the North Malabar and South Malabar in the erstwhile Malabar District. It is believed that until the 20th century, the Nair women of North Malabar were prohibited crossing the Korapuzha and going south or marrying a person from South Malabar. Those who violated the rule faced Bhrasht (Ostracism) and penalty of caste.
