The man, who appeared to be in the U.S. illegally, reportedly called 911 to report that he got injured and was “unable to walk further,” officials told Tucson's KVOA television.

It took nearly five hours for the agents to find the man stranded on the mountain, which peaks at 3,848 feet high and takes nearly seven hours to climb.
