The crash involving Utah National Guard UH-60 helicopters was reported southeast of the Snowbird ski resort just outside of Salt Lake City.
It happened during a routine mountain training exercise and they were supposed to land about 150 yards from the ski area, said Utah National Guard spokesman Jared Jones at a news conference Tuesday afternoon.
Both helicopters were damaged and the incident is being investigated,, the Utah National Guard said in a tweet.
Witness Robbie Shine told The Salt Lake Tribune he was about 200 yards from the crash site, while another group of people he saw were “within feet” of one of helicopters when it hit the ground.
“It was close. It was a pretty scary event,” Shine told the Tribune. “I think they were intending to be further away in the landing zone. ... Just glad everyone walked away.”
