A leading Nepalese climber, who’s scaled Mount Everest 19 times, is missing after an avalanche hit a group he was guiding on a smaller Himalayan peak. The agent in charge of the expedition says Chhewang Nima’s experience and survival skills means he could still be alive.
    The Nepalese mountaineer was fixing ropes near the summit of a 7,000-metre peak, Mount Baruntse, on Saturday when an avalanche hit. Another Sherpa, who was behind Chhewang Nima, reported that he was blown over the side of the mountain by the force of the snow. A rescue helicopter was sent to the scene but was unable to take off from the mountain’s base camp because of high winds.Another attempt will be made on Monday to reach the side of the mountain where the climber is believed to be.
