Marvin Edward Adair, 28, disappeared on November 1, 1972, after becoming separated from a hunting party in the Placer River Valley near Portage, Alaska. An experienced outdoorsman, he was carrying a rifle, a revolver, binoculars and other gear, and was dressed in a red or brown insulated vest with Adair sewn on the right breast, blue Levi jeans and a gold or brown wool Pendleton shirt when last seen.

Searches by official personnel and volunteers combed the area where he was last seen but turned up no trace of him. The search was eventually called off and the matter remains an open missing person case with the Alaska State Troopers. There is no evidence reported about what may have happened to him, and his fate remains unknown.

Did anyone in the Placer River Valley area in 1972 see or hear anything that could help explain what happened to Marvin Adair?
