Las Vegas Fire & Rescue reported a possibly deadly crash on Kyle Canyon Road on Mount Charleston around midnight on Saturday.
Two North Las Vegas men driving by found the victim trapped in his flipped-over vehicle in a ravine.
"First thing I did [when I got home] was kiss each one of my kids and my wife, then laid down and went to bed," said Michael Betts, one of the men. "That could've been me."
Betts and Roberto Davila made the unwanted discovery.
"I didn't want to get any closer," Davila said. "I thought the worst had happened."
They called 911 and waited.
"I felt helpless," Davila said. "They're telling me, 'Don't move him, don't touch him.' The car's upside down and it's still on. I'm asking, 'Can I turn off the car?' 'No, don't turn off the car.'"
Emergency crews got the man out and a helicopter took him to UMC.
Las Vegas Fire and Rescue officers didn't immediately respond to our questions about the victim's condition.
It's unclear what caused the rollover.
