It is imperative that the Tourist Map of India should be enriched by the inclusion of these geological monuments and alike, so that visitors, both domestic and international. can gain an insight in to the past – the formation of the subcontinent, the orogeny, the palaeoenvironment and the exotic collection of paleo – flora and fauna.
Geological Survey of India has undertaken the responsibility of protection and promotion of such features and has declared 34 such sites, located in different parts of the country, as National Geological Monuments.
