The Nanda Devi National Park , established in 1982, is a national park situated around the peak of Nanda Devi (7816 m) in the state of Uttarakhand in northern India. The entire park lies at an elevation of more than 3,500 m (11,500 ft) above mean sea level.
The National Park was inscribed a World Heritage Site by UNESCO in 1988. The latter was expanded and renamed to Nanda Devi and Valley of Flowers National Parks in 2005.
Within the National Park lies the Nanda Devi Sanctuary, a glacial basin surrounded by a ring of peaks between 6,000 metres (19,700 ft) and 7,500 m (24,600 ft) high, and drained by the Rishi Ganga through the Rishi Ganga Gorge, a steep, almost impassable defile.
The National Park is embedded in the 2,236.74 km2 (863.61 sq mi) sized Nanda Devi Biosphere Reserve, which, in turn, is encompassed in the 5,148.57 km2 (1,987.87 sq mi) buffer zone around the Nanda Devi and Valley of Flowers National Parks UNESCO site.
The first recorded attempt to explore the sanctuary was in 1883 by W. W. Graham, who could proceed only up to Rishi Ganga. Other attempts by explorers in 1870, (T. G. Longstaff) 1926, 1927 and 1932 (Hugh Ruttledge) did not fetch fruitful results. Eric Shipton and H. W. Tilman entered the inner sanctuary through Rishi Ganga in 1934, thus opening the extensive exploration in the sanctuary. In 1939, the area was declared as a game sanctuary.
The Nanda Devi Sanctuary within the National Park can be divided into two parts, Inner and Outer. Together, they are surrounded by the main sanctuary wall, which forms a roughly square outline, with high, continuous ridges on the north, east, and south sides. On the west side, less high but still imposing ridges drop from the north and south toward the Rishi Ganga Gorge, which drains the sanctuary towards the west.
The Inner Sanctuary occupies roughly the eastern two-thirds of the total area, and contains Nanda Devi itself and the two major glaciers flanking the peak, the Uttari (north) Rishi Glacier and the Dakshini (south) Rishi Glacier. These are fed by the smaller Uttari Nanda Devi and Dakshini Nanda Devi Glaciers respectively. This region was already inhabited by the aryanic, Mongolian and Himalayan indigenous peoples as per vedas and natural history but the first recorded entry of the British into the Inner Sanctuary was by Eric Shipton and H. W. Tilman in 1934, via the Rishi Gorge.
