The park and nearby town of Springdale was filled with missing person signs featuring pictures of Courtier and the clothes she was wearing.
Holly Suzanne Courtier, 38, of Los Angeles, was found Sunday by search and rescue crews after park rangers received a tip that she had been seen in the park, Zion National Park officials said in a news release.
Chambers texted that her mother was "too weak and disoriented" to walk out on her own or seek help. "This prevented her from being able to seek out help", Chambers wrote.
They said Courtier had since been reunited with her family and left the park.
Jillian Courtier-Oliver told ABC's "Good Morning America" that her sister had lost a lot of weight and had "bruises all over her body". They thanked park rangers, search teams and volunteers for their efforts.
"We are slowly introducing foods".
A vigorous search for 38-year-old Holly Suzanne Courtier had been underway after she failed to show up for a scheduled shuttle departure from the park October 6. "My mom's recovery is my top priority right now. We will continue to focus on her health and will update everyone when possible". Courtier, who had been dropped off for a hike earlier that day, was reported missing October 8, according to the National Park Service. "She made that a positive thing, said that gave her the time to get out, see the parks".
Chambers appealed for help from other hikers to help find Courtier but she said her mother was a fit, experienced hiker and a fighter who could survive for more than a week outdoors in all of Zion's rugged glory. She told KCBS-TV Channel 2 last week that Courtier had been visiting national parks across the country in a converted van after losing her job as a nanny during the pandemic.
Zion's 232 square miles contain "high plateaus, a maze of narrow, deep, sandstone canyons, and the Virgin River and its tributaries", the park service says.
