Search and rescue crews are scouring an area south of Revelstoke, B.C., for a man who was last seen almost a month ago.

Revelstoke B.C.

David Anthony Klammer,39, left his parent's home in Saskatchewan on Oct. 8, bound for his residence in White Rock, B.C.

A backpack thought to be Klammer's was found on Oct. 26 in the brush along the Twelve Mile logging road south of Revelstoke.

On Monday, his white, 2003 Subaru Impreza, was found parked along the same logging road. An RCMP air search earlier this week found no sign of Klammer.

He's described as six-feet two-inches tall, weighing 196 lbs, with brown hair and blue eyes and possibly wearing a brown leather jacket.
