KATHMANDU: Mountaineer Jim Morrison hopped left on his skis, sending trickles of snow down a sheer gully on the North Face of Mount Everest, then he hopped to the right, his breath heavy in the oxygen-thin air. Below him plunged 9,000 feet (2,700 meters) of snow, ice and rock — the most merciless ski run on planet Earth. It had never been skied, until Morrison did it. “It was a spectacular four hours of skiing down a horrific snow pack,” Morrison told The Associated Press Tuesday of his historic Oct. 15 run.
