KATHMANDU, SEPTEMBER 26 Renowned North Face athlete Hilaree Nelson went missing just below the true summit of Mt Manaslu while her partner Jim Marrison skied down the 8613-metre peak this morning, a source at the base camp confirmed. Missing ski mountaineer Hilaree Nelson found dead Manaslu Avalanche Update: One of five critically injured dead, two evacuated from Camp III Nelson reportedly fell into crevasse from just above the fore summit of the mountain when she along with Morrison skied from the real summit this morning. Nelson fell down around 25 metres into vertical crevasse and had gone missing, eyewitnesses said. Their Sherpa guides are at Camp IV now. Morrison has been skiing down from Camp III while filing this report, eyewitnesses said. Rescue operations are hampered by bad weather, sources said. The duo were part of the ski expedition managed by Shangri-La Nepal Treks. Hilaree and partner Jim had made the first ski descent of Lhotse, the fourth tallest mountain in the world, last year. According to the North Face, with a career spanning two decades that includes dozens of first descents through more than 40 expeditions to 16 different countries, Hilaree Nelson is the most prolific ski mountaineer of her generation. The 45-year-old mother of two was the first female to link two 8000m peaks, Everest and Lhotse, in one 24 hour push. In the fall of 2018, she returned to 27,940-foot Lhotse a second time to ski from the summit, linking turns down one of the most prized un-skied lines in the world, as per the TNF website.
