A desperate weeklong search for a missing 73-year-old hiker in the mountains of Southern California has ended with his rescue.

Eugene Jo was recovered in Angeles National Forests Devils Canyon on Saturday morning, exactly a week after he became separated from his hiking group on June 22.

The fact that he survived this long its amazing, Sgt. John Gilbert of the Los Angeles County Sheriffs Department told CBS Los Angeles .

Search teams of people across the state had combed through the area to find him while rescuers with all seven Los Angeles County search and rescue teams deployed search dogs, drones and helicopters to help, the Altadena Sheriffs Station said.
