Officials from Argentina's San Juan province found him living in a shelter 2,840 m above sea level when they went there to record snow levels.
Although the man had suffered significant weight loss, he opened the shelter's door and alerted the officials about his presence.
"The truth is that this is a miracle. We still can't believe it," San Juan Governor Jose Luis Gioja told the media.
"We let him talk to his wife, his mother and his daughter. I asked him: 'Are you a believer?' He told me, 'no, but now I am.'"
A doctor treating Gomez said he will be discharged soon.
