The Easton woman who was rescued after she tried to hike out for help when she and her family became stranded on a snowy northern Arizona road for two nights says she was determined to not leave her son motherless.

"I can't leave my son without a mom,'' Karen Klein told NBC about her motivation to keep going. "I can't leave my husband without a wife. I'm not letting my parents bury me. I was determined that this is not how my life is going to end."

She is recovering in a Utah hospital where she faces possible amputation of one or more frostbite toes.

"In the grand scheme of things," said Klein, "I keep thinking: 'You know what? It's a few toes. Don't worry about it.' "

Klein, 46, her husband, Eric, and 10-year-old son, Issac, were on a vacation  trip to the West when they set out Thursday for the North Rim of the Grand Canyon, which is closed for the winter, when their rent-a-car became stuck in a ditch.
"It was decided that there is a main road up ahead, and I have professional and recreational experience, a lifelong (experience) in the outdoors, so I said, 'I'll just go, I'll just walk up to the main road, I can do this, I'm a runner,' '' Klein told NBC.
When she didn't return to the car, her husband hiked to higher ground to get cellphone service to call for help, according to the Associated Press.
The father and son were rescued Friday, treated for exposure and released from a hospital in Utah.
Klein, a Northampton Community College assistant professor in biology who is a marathon runner and triathlete, hiked about 26 miles before she took refuge in a shuttered cabin.
She told rescuers she ate twigs, drank her own urine and did her best to stay awake in the freezing temperatures. She told NBC she had to hobble for miles after pulling a muscle in her leg.
Klein was found Saturday morning by search and rescue crews just before a major storm struck the area.
"Our guys are ecstatic. This is a save," Jim Driscoll, chief deputy for Coconino County, told the Associated Press. "We were able to get a family back together for Christmas. It could have gone very bad very, very easily."
