Beas in Himachal Pradesh
The Beas River (Punjabi: ਬਿਆਸ) is the second easternmost of the rivers of the Punjab. The river rises in the Himalayas in central Himachal Pradesh, India, and flows for some 290 miles (470 km) to the Sutlej River in western Punjab state. The river was also known as Arjiki or Vipas to the ancient Indians and the Hyphasis to the Ancient Greeks.
The present name Beas is thought to be a corruption of the word Vyas,the name of Veda Vyasa, the author of the great Hindu epic, the Mahabharata. The river is sometimes also referred to as Vipasha in Himachal, especially by the scholars. The Beas River marks the eastern-most border of Alexander the Great's conquests in 326 BC.
