http://www.adn.com/2012/06/16/2507310/four-climbers-killed-in-mckinley.html: Four Japanese mountain climbers are believed dead following an avalanche early Thursday morning on North America's tallest peak. The 800-foot slide came at about 2 a.m. as the five-person team was roped together, descending a main route down Mount McKinley, according to the National Park Service. Four of the climbers, all in their 50s and 60s, disappeared in the avalanche.
The lone survivor is a 69-year-old man who fell about 60 feet down a crevasse but scrambled to safety with no significant injuries.
