Stephen Michael Mason, 52, vanished from the Dungeness Forks Campground in Olympic National Forest after an outing with his wife in June 2006. An argument prompted Berwyn Mason to leave the campsite; on June 20 Stephen left to see a friend so the friend could return the couple’s vehicle and Berwyn’s belongings. The friend later drove Stephen back to the campsite and left him there. That was the last confirmed sighting.

Stephen’s mother reported him missing on June 29 after days without contact. Search-and-rescue teams and helicopters searched the rugged area; a cache of his food and supplies was found at the campsite untouched, but no trace of Stephen. Family members describe him as an experienced outdoorsman and a capable handyman; his failure to make his usual Mother’s Day call was noted as uncharacteristic. The family has a son and a daughter and has offered a reward for information. The Clallam County Sheriff’s Department lists the case as open; authorities say there is no link to Israel Keyes. No suspects or arrests have been publicly named.

Does anyone who knew Stephen, visited Dungeness Forks in June 2006, or remembers seeing someone matching his description around June 20 have information to share?
