Editor's note: This updates with Mr. Williams being found, and corrects park reports that he was due out on September 27. He had planned to return by Sept. 23, they said.

A search for a man overdue in the backcountry of Kings Canyon National Park was resolved when the man hiked out of the park on his own, park officials said Sunday.

Park officials said John Williams, 67, of Bishop, California, returned from his trek Saturday night. He had planned to return Sept. 23, they said, correcting earlier reports that he had been due out on Sept. 27.

Mr. Williams had managed to stretch his food to last the extra week in the park, they added, and he was in good health when he returned home. They did not say why he failed to return on schedule.
