Summary
Two experienced U.S. climbers, Gil Weiss and Ben Horne, have gone missing in the Cordillera Blanca mountain range in Peru. Their situation was reported and a search began after they were overdue to contact their families by two days.
Description
The crowdsourcing team, Tomnod, led by National Geographic Emerging Explorer Albert Lin, is assisting in the search for the mountaineers by asking the public to examine satellite images of the region in the hope that some trace of them can be found. They are also accepting donations to raise money for an air search of the region.
