Natural Arch Back to Geo Tourism

Natural Arch in Tirumala hills, Chittoor District, Andhra Pradesh

Natural Arch Geological agents like wind, water, ice act continuously on the rocks to erode and transport the disintegrated rock materials, bringing out marvellous changes in landscape. Natural Arch is one such unique geological marvel in the country measuring 8 metres in width and 3 metres in height. It has been curved out of quartzite of Cuddapah Supergroup of Middle to Upper Proterozoic (1600 to 570 Ma) by collective action of weathering agents like water and wind over a long period of several thousands of years.

Natural Arch Natural Arches of this kind are a rarity. The Rainbow Arch of Utah in the USA and the the one in the Dalradian Quartzite are the other examples.

Tirumala hills, Chittoor district is situated 10 km northwest of Tirupati town on Srikalahasti � Chittoor state highway. The Tirupati � Renigunta loop line connects it to the Chennai-Vijayawada main line of the South Central Railway.
