Yells spark hope in Snowy Mountains search YELLS have been heard high up in NSW's Snowy Mountains, offering fresh hope that a Canadian man missing for more than a week may still be alive. Prabhdeep Srawn's rental car was found on May 13, abandoned at Charlotte Pass ski village, on the slopes of Mount Kosciuszko. Police believe the former Canadian army soldier and Gold Coast law student was hiking up the mountain when he got lost in freezing and inhospitable terrain. Despite doubts about Mr Srawn's ability to survive for so long in such cold conditions, there was a glimmer of hope on Wednesday as search crews reported hearing yells. The calls sparked two searches of old stone survival huts - one in Lady Northcote Canyon, not far from Carruthers Peak and another at Etheridge Ridge. Crews aboard the Westpac Lifesaver Helicopter, which near the buildings, found nothing, but vowed to continue searching those areas. "Lifesaver Three landed close to Opera House Hut; engines shut down to listen for voices," the helicopter crew tweeted. Foot searching underway. Additional resources enroute. Search for Prabh continues. The helicopter also used a thermal imaging camera to search a series of gullies and ravines in the hope of locating Mr Srawn. Friends and family are also refusing to give up hope. But with more snow forecast in the days ahead, adding to the thick blanket which has already coated the mountain ranges, his chances appear slim. A friend of the Srawn family, Dr Tej Sehota, told ABC radio: "We remain optimistic - there's no reason not to feel anything but optimism. He's had training in extensive cold-weather camping with the Canadian Army, where they're basically doing forced camps for weeks at times in cold weather with minimal equipment.
