  • The Goddess Nanda and Place Names of the Nanda Devi Region
    The Goddess Nanda and Place Names of the Nanda Devi Region H. A dams Carter A L T HOUGH the goddess Nanda* (Devi means “goddess”) does not appear in the ancient sacred Hindu texts, that does not mean that she, a consort of Śiva, is not one of the important, if not the most important, of the Hindu deities in Garhwal. She permeates the whole area. In the region drained by the Rishi Ganga and the Dhauli Ganga, every nook and cranny seems in one way or other to be dedicated to her. The highest and most impressive mountain of the region, Nanda Devi, bears her name. Other peaks too bear her name. Within the Inner Sanctuary rises her bed (Nanda Khat) and nearby, her fortress (Nanda Kot) and her headdress (Nanda Ghunti). But her own name does not always appear. The name of the town of Lata has to do with “leg.” Lata supports the small mountain, above the town, Jipur, Nanda’s resting place. Thus, names which do not seem to the casual observer to be connected to the goddess are closely linked to her in the minds of the local people. They feel her presence everywhere. Ever since my first visit to the region forty years ago, I had associated the mountain Triśul (Trident) with Śiva’s deadly weapon. This year on two or three occasions my suggestion to the porters that the peak repre­ sented Śiva’s trident brought speedy denials. “No, sahib. Not Śiva’s but Nanda’s trident. When she needs to protect someone and becomes angry, she gets eight arms, each holding a weapon.

  • 236 the AMERICAN ALPINE JOURNAL and Towers Offer Scrambles, but in Winter the Sar Provide Remarkable Ski- Mountaineering
    236 THE AMERICAN ALPINE JOURNAL and towers offer scrambles, but in winter the Sar provide remarkable ski- mountaineering. The mountains of grass and scree become headwalls, ridges, long slopes of powder snow, chutes hundreds of meters long and gleaming with ice, great cornices, frost feathers a meter long. The Sar can be as good as anything you can find. STANLEYS.SHEPARD AFRICA Mount Kenya and Hell’s Gate Crag. Paul Braithwaite and I spent four weeks in East Africa. We visited Hell’s Gate Crag with the local hard-man, Ian Howell, who took us up the classic route of the crag Olympian. I managed to free-climb the pegging pitches. Braithwaite and I then went off to Mount Kenya and made a new direct route up the steep northeast face via the Grey Pillar. We made the climb in 15 hours with a bivouac midway up the route on continuously clean jam-cracks. Back at Hell’s Gate we teamed up with the other local hard-man, Ian Allen and put up two more new routes. During the last week we returned to Mount Kenya and climbed the fabulous Diamond Couloir via the steep headwall and continued on up to the Gate of the Mist and then to the top of Bastian, the highest point of Mount Kenya. We descended via Nelion and the Shipton route in a continuous 14-hour day. I wish to call attention to the earlier ascent of the whole of the Diamond Couloir by the American Phil Snyder and the local Vikuyu, Corporal Thumbi.

  • Classification of the Himalaya
    Classification of the Himalaya COMPILED BY H. ADAMS CARTER This study aims to classify the different groups of the Himalaya from its eastern end westward through the peaks of Garhwal (Uttar Pradesh) in India. Wherever data have been available, it gives a listing of all peaks above 6500 meters (21,326 feet) and all officially named peaks between 6000 meters (19,685 feet) and 6500 meters with altitudes and coordinates. In some ranges, where peaks are lower, some unnamed peaks in the second category have been included. The Nepalese section depends almost entirely on the outstanding work done by Dr. Harka Gurung and Dr. Ram Krishna Shrestha. These two Nepalese scholars put together an inventory of all Nepalese peaks above 6000 meters with the latest altitudes, corrected names and coordinates. They used primarily the Survey of India topographic sheets at a scale of an inch to a mile (1:63,360). They also used maps ar 1:50,000 prepared for the Sino-Nepalese Boundary Agreement of 1979. For the Indian regions, extensive use was made of three maps published by the Schweizerische Stiftung fur Alpine Forschungen (Swiss Foundation for Al- pine Research) of Sikkim, Garhwal East and Garhwal West. Harish Kapadia and Dhiran Toolsides in particular gave great assistance by checking Indian data against further information available to them. Colonel Lakshmi Pati Shanna made valuable suggestions. Dr. Shi Yafeng also helped by providing an excel- lent Chinese map of the Everest region. In all sections, the Japanese Mountain- eering Maps of the World proved indispensable. Dr. Zbigniew Kowalewski had made fine studies, which are reflected here.

A month on Trisul Sadashige Inada On 28 September 1978, we, the Himalayan Association ofjapan (HAj) Garhwal Himalaya Expedition, climbed Trisul Main Peak (7120m), Trisul II (6690m) and nnamed Peak (about 6100m), on the N ridge ofTrisul Main Peak, in only 10 days from establishing Base Camp. We first planned to visit Nun (7135m) in August 1978 and obtained climbing permission, but that permission was cancelled for an unknown reason in December 1977 by tbe Government of India. This was a blow to our plans and at once we sem Masato Oki, the Director of HAj, to India to obtain permission for Trisul Main Peak. This was refused also, since permission had already been given ro another expedition during Autumn 1978. We then asked for Trisul 11, and obtained permission for September/ Ocrober in 1978.

Read Full License Page 1/26 Abstract On 07 February 2021 around 10:30 hrs local time catastrophic ash ood occurred in the Dhauliganga River (a tributary of Ganga River) near Rini village at 2000m above msl (mean sea level) (Chamoli District), which killed 79 people and about 125 people are still missing. Part of the area belongs to Nanda Devi Biosphere Reserve which is completely protected from human interventions. Further, on Dhauliganga River, there were two run-of-river hydroelectric power Rishiganga Small Hydro (13.2 MW) at 1975m above msl and Tapovan Vishnugad (520 MW) at 1795m above msl projects which were also severely damaged due to the devastating ash ood. More than 150 workers were also trapped in the under construction power tunnel of Tapovan Vishnugad project. Further, it is important to note that the study area belongs to highly seismically active region and Zone-V Seismic Zoning Map of India which comes under highly vulnerable category. During last thirty years the region has also witnessed about 53 earthquakes (within 100km) of magnitude ranging Mw 3.2–6.6.
