(AP) Hitoshi Ogi was tied last in a line of five Japanese climbers making their way down one of the world's most dangerous mountains when an avalanche struck.

The rope snapped and the four people in front of him were swept away, either buried under three feet of snow or pushed into one of the deep hidden crevasses that pock the western face of Alaska's Mount McKinley.

Ogi, 69, tumbled 60 feet into a shallow fault in the mountainside and climbed his way out. He later told park rangers he looked around but couldn't find any of his companions.

Fourteen hours after Thursday's accident, Ogi stumbled into base camp. He had only minor injuries.

U.S. National Park Service said Saturday that the four are presumed dead by either snow burial or injuries suffered in the fall.

4 climbers presumed dead after Alaska avalanche

Ogi's survival came during the busiest season on Mount McKinley on its most well-traveled route. Search teams spent parts of Friday and Saturday looking for the other four climbers, all older than 50 and all members of the Miyagi Workers Alpine Federation in Miyagi, Japan.

Recent snow on the trail made the going hazardous, but the weather on Thursday was calm, said U.S. National Park Service spokeswoman Maureen McLaughlin.

"Where the avalanche occurred, the vast majority (of the new snow) was not on the main route," McLaughlin said. "A small sliver of it was, and that's what took them."

The West Buttress route snakes down the mountain from a 20,320 summit to base camp two-and-a-half miles below. About two-thirds of the way down is Motorcycle Hill, a windy ridge that serves as a convenient stop for climbers on their way up to grin and take pictures.

That's where the avalanche struck, taking 64-year-old Yoshiaki Kato, 50-year-old Masako Suda, 56-year-old Michiko Suzuki, and 63-year-old Tamao Suzuki.

McLaughlin called it "an unlucky, random event."
