(Portland, OR)  --  Environmental icon George Atiyeh remains missing after the Beachie Creek fire destroyed his home near Lyon last week.  Atiyeh's daughter Aniese Mitchell took to Facebook Friday night to announce her family has officially listed her 72-year-old father as a missing person in the Beachie Creek fire.  Mitchell tells the Oregonian she last spoke with her father a week ago Monday night, and that he'd been determined to stay in his home despite the fire.  Atiyeh is known for his work to block the U.S. Forest Service from clear-cutting the old growth forests around Opal Creek in the Willamette National Forest.  Congress passed legislation in 1996 protecting the area from logging.
