Marin County sheriff's deputies along with search and rescue teams on Thursday found a 16-year-old girl who was missing overnight on Mount Tamalpais.
Sarah Jane Tang and a friend went on a hike on the Rock Springs Trail around 12 p.m. Wednesday, deputies wrote on the Twitter. The pair got separated, but crews found the other girl around 9:30 p.m. because her phone was working at the time.
Sarah, who was reunited with her father, was also carrying her cell phone, but it died overnight so she wasn't able to call for help.
Around 30 people combed the area starting around midnight, deputies said. However, the darkness and then the fog posed challenges.
