Rajasthan is the largest state in the Indian Union. Geographically, the land of Rajasthan is more varied than any other region. It is a region of lofty rocks, rolling sand dunes, of burning heat and freezing cold, of fertile plains and deep wild glens and jungles. The Aravalli range, which is the oldest folded range in the world, divides the area into two natural divisions-North-West and South-East. North-West area is a sandy and ill watered tract emerging gradually from a mere desert in the west and North-West to comparatively fertile land towards the East and North-East in the neighborhood of the Aravallis and the track bordering Haryana.
Rajasthan relentlessly touted as the Desert State of India, covers some 342,000 sq km in the north-western region of India. The state isn’t just about drifting sand, never-ending dunes and barren scrubland as parts of it are surprisingly green, especially after a generous monsoon. The sandiness is confined to the west and southwest, while the Aravallis, a range of craggy hills, slash the state effectively into two. Politically it is divided into six administrative zones: Mewat , Marwar , Mewar , Dhundhar , Hadoti.
