Charles Thomas Denny was 35 when he was last seen on September 30, 1981, in Salton City, California. According to his roommate, Denny went into the desert near Harper’s Well, off Highway 78, to search for treasure and never returned. His vehicle was later found abandoned in that remote area, but no sign of Denny has ever been located.

Denny was described as 5 feet 8 inches, about 150 pounds, with brown hair and blue eyes. At the time he disappeared he wore square-shaped, gold wire-framed glasses. Extensive searches of the desert turned up no further evidence to explain what happened; given the harsh environment and the circumstances, investigators have considered both accident and foul play but reached no definitive conclusion.

Does anyone who spent time around Harper’s Well in 1981 or knew Charles have information that could help explain his disappearance?
