Jadh Ganga river gorge, on the road to Gangotri (India)
The Jadh Ganga is a tributary of the Bhagirathi river, one of the headstreams of the Ganges.
Jadh Ganga originates in Tibet, China, north of Mana Pass. The upper valley of Jadh Ganga is claimed by China and controlled by India. For more info, read en.wikipedia.org/wiki/Jadh_Ganga.
I took this photo from a bridge over this narrow canyon.
