The 18-year-old had fallen 30 feet from a cliff.
The mother, Shelly LaGrou, said yesterday that she waited, roughly 2,400 kilometres away in Omak, Washington, to hear her daughter's voice again.
"I'm still living it," she told The Associated Press in a phone interview.
Daughter Cherelle LaGrou, who is working in Alaska this summer, came back on the phone after a while, saying she had slipped down the slope and couldn't climb back up. She was hysterical and crying, telling her mother she wasn't ready to die.

That call set in motion a dramatic 45-minute rescue near Denali National Park that was captured by the National Geographic Channel reality show "Alaska State Troopers." It's expected to air this fall.
The teen said that before her rescue, she believed she was staring death in the face and thought about everything she would miss in her life.
Instead, she sustained only minor scratches.
"It feels like it was something out of a movie," she said, laughing when reminded that in a way, it was. "It was all just so unreal that it was actually happening."
She told her mother she had reached the edge of the mountain and didn't know what to do. Then came the scream. When the teen came back on the phone, she was hysterical and said her feet kept slipping. In that position, there was no way she could have called for help herself, Cherelle LaGrou said.
Mother and daughter prayed together that angels would hold the teenager against the wall of the mountain.
