(CNN) Hiker Holly Courtier, who was rescued after disappearing for almost two weeks in Utah's Zion National Park, spent the night in a medical center near Zion, a family friend said.
She was very dehydrated and malnourished," Kelley Kaufman White told CNN hours after Courtier was found.
The National Park Service dispatched a rescue team after park rangers received a "credible tip" on her whereabouts, it said.
Chambers, who became concerned when she hadn't heard from her mother in a week, traveled the almost 500 miles from San Diego to Zion to help find her mom and appealed to other hikers to join the effort.
