Charles Duke, with a female companion, was driving on an unpaved mountain road to the Vogel Canyon Picnic Area when their vehicle became high centered and stuck. Unable to get their vehicle unstuck, they sete off on foot to find the picnic area. After wandering around for several hours they split up. Charles Duke went off alone to find the picnic area while the female companion stayed put. That was approximately noon on August 18, 2003. That was the last time Charles Duke was seen. An extensive search on foot and by air failed to find Charles Duke.
