That 6,110-meter ( 20,000-foot ) tall mountain is located in a region popular with climbers in Huaraz province about 275 miles northeast of Lima . `` These are two of the finest climbers we have known ... embodying the spirit of the mountains with every thing they did , '' an announcement on Tomnod 's site said . `` Many of us have had the honor of sharing in their love for the wilderness , and that lives on .

'' What is altitude sickness ? On July 10 , Horne posted pictures and a chronicle of their experiences on the climbing blog Pullharder.org . `` The Cordillera Blanca is world renowned for its high altitude mountaineering , '' he wrote . `` But almost as awesome as the mountains themselves is the motley crew of international climbers who come to try their hand at getting high , on big peaks , cheap and fast . '' According to a blog post on Tomnod 's site Saturday , Weiss and Horne were missing for the past five to 10 days . Kari Tenjford , a friend of theirs , wrote on his Facebook page that a search team found the two climbers ' tent , as well as tracks up the glacier and `` tracks on the descent ridge . '' Har-Noy said he enlisted the help of climbers and technology experts alike to find the pair using an application he built , with hundreds of people at one point poring through satellite images looking for signs of an avalanche . That information was then sent to search and rescue crews in Peru , said Har-Noy . Another friend , Asa Firestone , said the climbers ' bodies were ultimately found `` after what looks to be a fall from the ( southwest ) ridge on their descent .
