Rodney Trumbo, 55, was reported missing on November 8, 2013, after he went into a canyon off the Rim of the World Highway in the San Bernardino Mountains near Crestline, California. He had gone there with a friend to look for a lost backpack, wallet, and keys; the friend reportedly last saw him during that search. Trumbo had no cell phone activity after the day he disappeared and did not return home by 8 p.m., prompting his girlfriend to report him missing.

He is described as about 5 feet 5 inches tall, 140–150 pounds, with brown hair and blue eyes. At the time he vanished he was wearing denim blue jeans and white socks. Family, law enforcement and volunteer searchers conducted extensive efforts in the rugged terrain but found no trace of him. The difficult mountainous landscape and the passage of time have left the case unresolved.

If anyone was in the Crestline area on November 8, 2013, or has information about that canyon search, please come forward.
