woman spent four nights trapped in her mangled truck after she swerved to avoid hitting a deer and toppled to the bottom of a California canyon.

She was driving near Mount Baldy on Wednesday on a road that winds up the mountain outside Los Angeles. Her pickup truck fell 250 feet onto the embankment, leaving her trapped with a broken ankle in freezing temperatures, according to the San Dimas Mountain Rescue Team.

With no cell service, the woman had no way to call for help, the rescue team said. She survived off the supplies she had in her car.
