A flightseeing plane carrying Polish passengers crashed near the summit of the Thunder Mountain ridgeline in Denali National Park on Saturday.
On Monday, a National Park Service (NPS) ranger was lowered down to the crash site from a line from a helicopter. The ranger dug through snow and found the bodies of four of the five passengers, NPS said in a press release.

The study was published in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union in March. The Earth science organization released details about the research Tuesday.
