Denali, North America's tallest mountain, is seen in August 2016.
- Four Polish tourists were found dead on Monday after a sightseeing airplane crashed in Alaska's Denali National Park.
- One person is still missing and presumed dead after the Saturday evening crash.
- Pilot Craig Layson was taking a group of four tourists on a one-hour tour of Kahiltna Glacier, the starting off point for many trying to climb Denali, North America's tallest mountain.
- They crashed around 6 p.m. near the top of Thunder Mountain, which rises nearly 11,000-feet above the glacier.
Searchers said Monday they found four people dead in a sightseeing airplane carrying Polish tourists in Alaska's Denali National Park - a day and a half after thick clouds hampered the response to a distress call.
Another person is missing and presumed dead after the crash Saturday evening on a mountain ridge about 14 miles southwest of Denali, North America's tallest mountain.
After going down, the pilot, Craig Layson of Saline, reported by satellite phone that passengers suffered injuries but the connection failed before he could give details.
The airplane was stocked with sleeping bags, a stove, and food, giving hope that survivors would be found despite terrain described by the National Park Service as "extremely steep and a mix of near-vertical rock, ice and snow."
Low-lying clouds and rainy conditions prevented crews from spotting the wreckage until clearer weather on Monday allowed a helicopter to reach the crash site. A park service ranger descended by short-haul line.
The ranger dug through snow that had filled the aircraft and found the bodies of four people. There were no footprints or other disturbances in the snow that would have indicated anyone made it out of the plane, the park service said.
The de Havilland Beaver plane, operated by K2 Aviation, had taken off on Saturday around 5 p.m. with a pilot and four passengers from Poland for a tour of Kahiltna Glacier, the jumping off point for many climbers attempting to scale Denali.
It crashed about an hour later near the top of 10,900-foot Thunder Mountain, which rises above the glacier. The park service describes it as more of a mile-long ridge than a mountain.
Climbing season on Denali has ended, but sightseeing flights can still land on the glacier, allowing visitors to walk on the ice field, park service spokeswoman Katherine Belcher said.
