Gangotri At a distance of 105 km from the town of Uttarkashi lies Gangotri, the spiritual source of the Ganges river, though its actual source is the ice cave of Gaumukh, 18 km up the Gangotri glacier. Here, Ganga is known as Bhagirathi, named after the ancient king Bhagirath who prayed to bring her down from the heavens. Another major tributary, the Alaknanda emerges from near Badrinath and joins the Bhagirathi at Devprayag to become the magnificent Ganga. http://www.indiayogi.com/content/pilgrimages/dham.asp
