A legally blind hiker who was lost on the Appalachian Trail for six days was found alive and healthy Saturday afternoon.

He was found after he lit a signal fire, his colleague at Backpacking Light and a member of the search party, Ryan Jordan, told the Ann Arbor News. The fire, which burned out of control and turned into a two-acre brush fire, prompted firefighters and other rescuers to go to his location near Snowden, Virginia.

Kenneth Knight, 41, who works for the outdoors magazine Backpacking Light, missed a planned rendezvous with fellow hikers last Tuesday and missed his flight back home on Wednesday night. He had been last seen Sunday morning, around 9 a.m. His friends reported him missing Wednesday.

The search party for Knight included about 130 people from several organizations.

Jordan said Knight can see shapes about 10 to 15 feet in the distance.

Knight was taken to the Lynchburg General Hospital Saturday night, but his friends say he is in good condition.
