A 34-year-old woman stranded for two nights in frigid temperatures after being severely injured in a fall on California’s Mt. Whitney has died at a hospital.

Cassandra Bravo was on a day hike Nov. 5 when she slipped and fell about 100 feet (30 meters) down a rocky slope, her friend Luisa Moya said.

Bravo was rescued Saturday after sheltering herself underneath a log, she said.

“She survived two very cold nights and was alive when they rescued her,” Moya said.

Bravo was rushed to a hospital where she died hours later, the news station reported Wednesday.

Bravo, the single mother of a 10-year-old son and 7-year-old daughter, worked as a nurse at Loma Linda University Medical Center in San Bernardino County.

“I got to hug her and tell her I loved her and tell her goodbye,” said her son, Jonathan. “She meant everything to me.”
