Palakkad Gap or Palghat Gap is a low mountain pass in the We | Kerala
Palakkad Gap or Palghat Gap is a low mountain pass in the Western Ghats between Coimbatore in Tamil Nadu and Palakkad in Kerala. It has an average elevation of 140 metres (460 ft) with a width of 24–30 kilometres (15–19 mi). The pass is located between the Nilgiri Hills to the north and Anaimalai Hills to the south.
There are various theories about the origin of Palakkad gap. One among them is that it is caused by the landslide due to rivers flowing in opposite directions. The Bharathappuzha river (River Ponnani) originates in the Palakkad Gap from rivulets and tributaries feeding from steep escarpment slopes along the flanks of the Ghats. Another theory suggests that the gap may be created by an asteroid strike around 800 million to 550 million years ago.
The Palakkad gap has played a major role in enabling human migration into Kerala from parts of Tamil Nadu. From 300 B.C. to 13th century, it also helped the Cheras rule the entire Kerala and the Kongu Nadu as one geographical unit from Karur in Western Tamil Nadu. Tamil Brahmins migrated to Palakkad from Central Tamil Nadu via the Palakkad gap from the 15th century to 18th century. ━━━━━━━━━━━━━ @Kerala | @Malayalam
