The Shivalik Hills, also known as the Sivalik Hills and Churia Hills, are a mountain range of the outer Himalayas.
Shivalik Hills stretch over about 2,400 km (1,500 mi) from the Indus River eastwards close to the Brahmaputra River, spanning the northern parts of the Indian subcontinent.
Shivalik Hills are 10–50 km (6.2–31.1 mi) wide with an average elevation of 1,500–2,000 m (4,900–6,600 ft).
“Sivalik” literally means ‘tresses of Shiva’. The Shivalik Hills are the Himalayas’ southernmost hills.
It is separated from the Lesser Himalayas by valleys with flat bottoms. The ancient name for this range was “Upgiri.” The Shiwaliks are the Himalayas’ most isolated range.
