Uttarkashi district in the context of Tehri Garhwal district

Chamoli district is a district of the Uttarakhand state of India. It is bounded by China's Xizang Autonomous Region to the north, and by the Uttarakhand districts of Pithoragarh and Bageshwar to the east, Almora to the south, Pauri Garhwal to the southwest, Rudraprayag to the west, and Uttarkashi to the northwest. The administrative headquarters of Chamoli district is in Gopeshwar.

Chamoli hosts a variety of destinations of pilgrim and tourist interest including Badrinath, Hemkund Sahib and Valley of Flowers. The Chipko movement was first started in Chamoli.

Yamunotri, also Jamnotri, 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 150 kilometres (93 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 Chota 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 the Bandarpunch mountain. The chief attraction at Yamunotri is the temple devoted to the Goddess Yamuna and the holy thermal springs at Janki Chatti which is 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.

Gomukh, also known as "Gaumukh" or "Gomukhi" (Hindi: गौमुख or गौमुखी ; Assamese and Bengali: গোমুখ or গোমুখী), is the terminus or snout of the Gangotri Glacier and the source of the Bhagirathi River, one of the primary headstreams of the Ganga River. The word Gomukh/Gaumukh (go/gau=cow, mukh= mouth) literally means "Mouth of a Cow."

The place is situated at a height of 13,200 ft (4,023 m) in the Uttarkashi district in the state of Uttarakhand, India. It is one of the largest glaciers in the Himalayas with an estimated volume of over 27 cubic kilometers.
