The Associated Press reports that searchers found a plane door Wednesday while hunting in rugged mountains for missing adventurer Steve Fossett, but say it doesn't appear to be from the small plane he was flying when he disappeared last year.

Search team spokesman Keith Szlater said the plane door isn't made of the same material used on the fabric-and-aluminum-frame plane Fossett was flying. He added that it appears to be too old to have come from Fossett's plane. No other aircraft debris was found.

The door was found by searchers, led by Canadian geologist and adventure racer Simon Donato, near Mount Patterson, at 11,673 feet the highest peak in the Sweetwater Mountains on the Nevada-California border. It was hauled out and will be turned over to authorities.

Fossett was declared legally dead in February, five months after he was last seen taking off by plane from a remote Nevada ranch owned by hotel magnate Barron Hilton.

The search team is focusing on remote canyons and wooded areas in the Sweetwaters and nearby Bodie Hills, near where Fossett was last seen. The area, about 110 miles south of Reno, could conceal wreckage not visible to the many private and military planes that searched last year.
