The Thar Desert extends between the Aravalli Hills in the northeast, the Great Rann of Kutch along the coastline, and the alluvial plains of the Indus River in the west and northwest. Most of the desert is covered by huge shifting sand dunes that receive sediments from the alluvial plains and the coast. The sand is highly mobile because of strong winds that sweep across the open expanse at the onset of the monsoon. The Luni is the only river integrated into the desert. Rainfall is limited, only 100–500 mm per year, quenching the thirst of the sand between July and September.
