( CNN ) -- Swedish mountaineer and professional skier Fredrik Ericsson died Friday while trying to summit K2 in Pakistan , his friend David Schipper told CNN in a telephone interview . The incident occurred between 7 a.m. and 8 a.m. as Ericsson was attempting to become the first man to ski from the summit to base camp , said Schipper , who said he learned of the accident on the world 's second-tallest peak in a satellite call from fellow climber Fabrizio Zangrilli . Ericsson , in his mid-30s , was at a place called the bottleneck , at an altitude of around 8,300 meters ( 27,231 feet ) , between Camp 4 ( 8,000 meters ) and the summit ( 8,611 meters ) , said Schipper , a Moab , Utah-based climber . He described the bottleneck as a `` steep and narrow section with thousands of meters of exposure below . '' Ericsson , along with his climbing partners Trey Cook and Gerlinde Kaltenbrunner , had begun the summit push between 1 a.m. and 1:30 a.m. in low-visibility weather . After several hours of climbing , they approached the bottom of the bottleneck . At this point , Cook returned to Camp 4 , leaving Kaltenbrunner and Ericsson to continue their ascent . As Ericsson was attempting to fix ropes to the snow and ice along the route he `` lost his purchase and was unable to arrest his fall , '' Schipper said . Ericsson 's body , resting at about 7,000 meters , will remain where it fell , Schipper said on Ericsson 's website . `` His parents have requested it remain in the mountains he loved , '' he wrote . `` Retrieval would be exceptionally dangerous . ''
NEW : Skier 's body will not be recovered . Incident occurred as Ericsson approached summit . He `` was unable to arrest his fall '' Ericsson was trying to reach top of K2 .
