Fred Lincoln Gist, 66, disappeared on August 19, 1975, during a multi-day horseback trip in Kings Canyon National Park near Cedar Grove, California. He and two companions overshot their planned campsite by a few miles and were advised by a packer to backtrack. Gist, feeling too tired, stayed behind with food and a poncho while the others took his horse and returned to get him the next morning.

When they came back, Gist was gone; a campfire and food wrappers showed he had eaten. Dogs, helicopters and ground teams searched for several days but found no trace.

Does anyone have information about Gist’s final movements or the area where he was left?
