ACHIEVEMENT// Twenty-three-year-old twins from Sonepat, Haryana — Nungshi and Tashi Malik -- have gone where few have managed to reach before. The sisters completed the Explorers Grand Slam, which involves reaching the North and South Poles, as well as scaling the highest peaks spread across seven continents. The girls took to serious climbing only in 2009, but in six years, they have accomplished what many veteran (experienced) explorers have failed to do. After completing an advanced course in mountaineering in 2010, the twins scaled Mount Kilimanjaro (Africa), in February 2012. They then set their sight on Mount Everest, which they scaled on May 19, 2013. This was followed by expeditions to Mount Elbrus (Europe) in August 2013; Mount Aconcagua (South America) in January 2014; Mount Carstensz Pyramid (Australia) in March 2014; and Mount McKinley (North America) on June 4, 2014. Perhaps the toughest leg of the Slam was the last – a 120-km ski trip to the North Pole, where they were weighed down by 45 kg of gear and had to ski 10 hours a day in freezing weather against strong winds. The twins emerged victorious, completed the Slam, thus earning a mention in the Guinness Book of World Records and making India proud.
