Recently the Supreme Court has announced that the state of Rajasthan can ban mining in the environmentally sensitive Aravalli range. Stretching for 670 km in north-western India, the Aravalis are one of the oldest folded mountains in the world, hosting diverse ecosystems. Guru Shikhar, its highest peak at 5,650 feet, overlooks Mount Abu, a popular hill station. The range serves as a geological boundary, separating the Thar Desert from eastern Rajasthan.
