[8] Anamudi has a topographic prominence of 2,479 metres (8,133 ft), the associated key saddle being over 2,000 kilometres (1,200 mi) away at 28°35′20″N 76°27′59″E / 28.58889°N 76.46639°E / 28.58889; 76.46639 in Haryana state just to the west of Delhi.

This geologic province represents an area of Archean rocks that were deeply buried during the neoproterozoic Pan-African Orogeny, as part of the Mozambique Belt, in which developed Himalayan-scale mountains when West and East Gondwana collided due to the closure of the ancient Mozambique Ocean.

After approximately 800-500 million years of burial, the Munnar Granite of the Anamundi massif is now exposed high above sea level due to a combination of faulting and unroofing.

[12] Anamudi and the Eravikulam National Park surrounding it is home to the largest surviving population of the Nilgiri tahr.

[15][16] The summit of the Anamudi is vegetated with patches of stunted Kuruna densifolia and Gaultheria fragrantissima (wintergreen), Anaphalis, Impatiens and Eriocaulon.
