Nine-year-old Kaamya Karthikeyan became the youngest person to reach the summit of the 6,153 metres-high Mt Stok Kangri in Kashmir earlier this week. Reaching the peak involved climbing 30 km over a course of three days, with an altitude gain of 2,750 metres. In May this year, Kaamya had successfully reached the base camp of Mt Everest at 5,464 metres.
