Steven Michael Clark Jr., 21, was last seen July 9, 1995, when he left Long Beach, California, for a camping trip with friend Burt O’Ryan Dollar. They were reportedly heading toward the south side of Yosemite National Park in a white Ford Festiva with Indiana plates. The vehicle was later found abandoned off Highway 395 near the California–Nevada border, but neither man was at the scene.

Clark is described as a Caucasian male with blond hair and blue eyes, about 5 feet 11 inches and 165 pounds. His disappearance has been classified as endangered missing. Despite extensive searches, no further clues were reported and both Long Beach Police and the San Bernardino Sheriff’s Department remain involved in the investigation.

What information might help locate Clark or Dollar, or explain what happened after their vehicle was found abandoned?
