Mana Pass
Mana Pass() or Chongnyi La() is one of the highest vehicle-accessible passes in the world, containing a road constructed in the 2005-2010 period for the Indian military by the Border Roads Organisation and visible on 2011 imagery on visual globe systems such as Google Earth. The well-graded gravel-dirt road is higher on the Indian side than the new road on the Tibetan side, and rises to on the Indian side of the border, 250 m west of the low point of the Mana Pass SRTM. Geography. Mana Pass is located within the Nanda Devi  Biosphere Reserve, 47 km north of the town of Mana, India and 52 km north of the Hindu pilgrimage town of Badrinath in Uttarakhand. It is the source of the Saraswati River, the longest stem of one of the longest Ganges tributaries, the Alaknanda River. That river trickles through several scenic small ponds between the pass and Lake Deo Tal three km southwest of the pass. Mana pass is also the key col for climbing Chaukhamba peak. Mana as a name derives from "Manibhadra Ashram", the ancient name of the town of Mana. History. Mana Pass was an ancient trade  route between Uttarakhand and Tibet. Mana Pass led from Badrinath to the kingdom, now province, of Guge in Tibet. The Portuguese Jesuits António de Andrade and Manuel Marques became the first known Europeans to enter Tibet across Mana Pass in 1624. The pass continued as a minor trade route until its closure in 1951 by the Chinese. On April 29, 1954, China and India signed an agreement granting pilgrims and indigenous travelers the right to travel between the two countries through Mana Pass. Access. The pass is reached from the south by an extension of India National Highway 7 (NH-7 , old number NH-58) that connects Fazilka with Badrinath, though beyond Badrinath the graded road is subject to landslides. Group of enthusiast motorcycle riders often can be seen on this road. Free Souls Rider Motorcycle Club was first non military citizens to scale the heights of Mana Pass and hold the record in The Limca Book Of Records.
