Grand Canyon National Park rangers are searching the park's backcountry for a missing California hiker.
Park spokeswoman Emily Davis says air and ground crews are looking for 72-year-old Raafat "Ralph" Amin Nasser-Eddin of Los Angeles along the Hermit Trail and several other trails.
Davis says Nasser-Eddin was reported overdue Tuesday evening and that he matches the description of a person reported to park rangers Sunday as being disoriented at the Hermit Camp camping area in the canyon.
Davis says a member of the park's search and rescue team unsuccessfully looked for that person Sunday and Monday.
According to Davis, Nasser-Eddin had a reservation to stay at Phantom Ranch along the Colorado River at the bottom of the canyon but did not check in.
