SAN DIEGO (FOX 5/KUSI) -- A woman is alive after being found stranded in a steep, rocky area several miles deep on a trail in San Diego's backcountry after she was missing for nearly two days. Deputies with the San Diego County Sheriff's Rural Enforcement Division received a call from the family of an unidentified 50-year-old woman around 2 p.m. Saturday after they said they had not heard from her since 8:30 a.m. on Friday. Police say she had texted family members at that time that she was starting a hike near the Lake Morena campground in Campo.
