Search teams recovered a 13th body Saturday from the snow and ice covering a dangerous climbing pass on Mount Everest, where an avalanche a day earlier swept over a group of Sherpa guides in the deadliest disaster on the world's highest peak, according to AP. Another three guides remained missing, and searchers were working quickly to find them in case weather conditions deteriorated, said Maddhu Sunan Burlakoti, head of the Nepalese government's mountaineering department. But the painstaking effort involved testing the strength of newly fallen snow and using extra clamps, ropes and aluminum ladders to navigate the treacherous Khumbu icefall, a maze of immense ice chunks and crevasses. The avalanche slammed into the guides at about 6:30 a.m. Friday near the "popcorn field," a section of the Khumbu known for its bulging chunks of ice. The group of about 25 Sherpa guides were among the first people making their way up the mountain this climbing season. They were hauling gear to the higher camps that their foreign clients would use in attempting to reach the summit next month. One of the survivors told his relatives that the path had been unstable just before the snow slide hit at an elevation near 5,800 meters (19,000 feet). The area is considered particularly dangerous due to its steep slope and deep crevasses that cut through the snow and ice covering the pass year round. -- SPA 20:58 LOCAL TIME 17:58 GMT تغريد
