Gil Weiss free-soloing Blitzen Ridge in Rocky Mountain National Park.
"Ugh, not 2 more," wrote one commenter on SuperTopo yesterday in response to news that two climbers from Boulder had gone missing during an ascent of a peak in northern Peru. Gil Weiss, 29, and Ben Horne, 32, were attempting the west summit of Palcaraju (20,046 feet), a rarely-climbed mountain in the Cordillera Blanca. When they still hadn't turned up five days after their prearranged return date, two teams, including one from Peru's alpine rescue group, set out to search for them. On Thursday, searchers discovered the partners' tent, along with tracks descending from the summit, and, most disconcertingly, signs of an avalanche.
