NOIDA: City boy Arjun Vajpai and his mountaineering partner Bhupesh Kumar have become the first to etch their names on a 'six-thousander' peak that overlooks the beautiful Spiti Valley and keeps a regal watch on the picturesque Himalayan landscape from an altitude of over 19,000 feet.The 'virgin peak', as Vajpai and Kumar call it, is near the Bara Shigri glacier, and the objective of summiting an unexplored peak was to inspire youngsters to take up mountaineering. They have named the peak Mount Kalam in the memory of the former Indian President.'Six-thousander', in mountaineering terms, is a peak that is 6,000 metres high or taller.Vajpai and Kumar (30), who is from Bulandshahr, completed their mission on October 14. "It is a technically challenging mountain with lots of deep snow, hidden crevasses and abundant rock. Climbing the mountain in an extremely cold environment was difficult. But we scaled it successfully," Vajpai told TOI from his Noida home. The two returned from their expedition on October 20.Vajpai said there are around 300 peaks in the country which are 'six thousanders'. "There is a lot of opportunity to explore these mountains. We decided to summit the virgin peak to motivate the young generation," Vajpai, who had climbed Mount Everest in May 2010, said.Vajpai had also attempted to summit Mount Makalu in Nepal in May but returned after he was stranded there due to the massive earthquake.Vajpai and Kumar had left Noida on October 8 and reached Batal camp in Himachal Pradesh on October 9. From there, they climbed to Scout Camp (4,100 metres), Intermediate Camp (4,400 metres), Base Camp (4,750 m) and Summit Camp (5,500 metres). On the morning of October 14, they scaled the peak (6,180 metres) and hoisted the Tricolour.Kumar said so far he has scaled 17 peaks in India. "The idea was to explore the virgin peak as no one knows about it," he said.On their way to the summit, they also encountered fog. "It was a challenging task. We had informed officials of the Indian Mountaineering Foundation and our friends about our journey so that they could keep a tab on our movement," Vajpai said.
