Yamunotri is the source of the Yamuna River and the seat of the Goddess Yamuna in Hinduism. It is situated at an altitude of 3,293 metres (10,804 ft) in the Garhwal Himalayas and located approximately 30 kilometers (19 mi) North of Uttarkashi, the headquarters of the Uttarkashi district in the Garhwal Division of Uttarakhand, India. It is one of the four sites in India's Chhota Char Dham pilgrimage. The sacred shrine of Yamunotri, source of the river Yamuna, is the westernmost shrine in the Garhwal Himalayas, perched atop a flank of Bandar Poonch Parvat. The chief attraction at Yamunotri is the temple devoted to the Goddess Yamuna and the holy thermal springs at Janki Chatti (7 km. Away).
The actual source, a frozen lake of ice and glacier (Champasar Glacier) located on the Kalind Mountain at a height of 4,421 m above sea level, about 1 km further up, is not frequented generally as it is not accessible; hence the shrine has been located on the foot of the hill. The approach is extremely difficult and pilgrims therefore offer puja at the temple itself.
The temple of Yamuna, on the left bank of the Yamuna, was constructed by Maharaja Pratap Shah of Tehri Garhwal. The deity is made of black marble. The Yamuna, like the Ganges, has been elevated to the status of a divine mother for the Hindus and has been held responsible for nurturing and developing the Indian civilization.
