Searchers in Alaska continue to search for two men who authorities say likely fell while climbing a mountain in Denali National Park.

Eli Michel, 34, and Nafiun Awal, 32, are not at Moose’s Tooth, which has a peak of 10,300 feet. They were reported missing Sunday, the National Park Service said.

Authorities believe the two men likely fell on Friday, the park service said in a statement.

An empty tent was seen and boot tracks led to a flagstone avalanche site, he said.

«Several pieces of the climber’s equipment were also sighted along the 3,200-foot drop line, including two ice axes and a climbing helmet,» the statement said.

Denali National Park covers 6 million acres and is famous for Denali, a 20,310-foot-tall mountain that is the highest peak in North America.

Moose’s Tooth is located in Ruth Gorge, which the park says is known for its sheer walls of rock and ice.

Michel, of Columbia, Indiana, and Awal, of Seattle, last checked in with a friend at 5 a.m. Friday using a satellite communication device, the park service said.

The searchers found their skis and tracks from where they switched to crampons. The tracks entered a small avalanche area, she said.
