In this Friday, June 15, 2012 photo provided by the National Park Service, climbers hike through the area where an avalanche swept a Japanese climbing team off a hill during their descent from Alaska's Mount McKinley. U.S. National Park Service officials say five people were traveling as a one rope team early Thursday morning as part of a Miyagi Workers Alpine Federation expedition on the Alaska mountain. The NPS said Hitoshi Ogi, 69, survived after falling 60 feet (18 meters) into a crevasse. He was able to climb out. The other four tumbled into the avalanche debris and haven't been seen since.
