ANAMALAI HILLS, ERAVIKULAM AND MUNNAR (KERALA)
It is also called as Elephant Hills. It is a range of mountains in the Coimbatore District of Tamil Nadu, located along the Western Ghats, lying between 10Â° 13′ and 10Â° 31′ N. and 76Â° 52′ and 77Â° 23′ E. It is also the tallest of the hills in South India that rises up to 8850 ft. The geological formation is of metamorphic gneiss, veined with feldspars and quartz, and interspersed with reddish porphyrites. The Lower slopes yield valuable teak and other timber. In some areas, coffee plantations are a common sight. The area was notified as Anaimalai Wildlife Sanctuary in 1974 and established in 1976.
There is a 30 Km wide gap [big break in the Western Ghat mountain range] between the Nilgiri Hills to the north and the Anamalai Hills to the South that straddles the Kerala and Tamil Nadu border and serves as a major communication route between them. Highways and Rail Transport connect Palghat with Coimbatore and Pollachi. This huge gap is called as Palghat Gap.
