A massive fire destroyed the Whitsell wood products manufacturing plant in the community of Saginaw, north of Cottage Grove.
The fire was reported at around 7:30 p.m. Sunday and engulfed the mill within 30 minutes.
Lane Fire Authority Chief Terry Ney says flames could be seen from a half-mile away. Billowing plumes of smoke rose into the evening sky and could be seen from Eugene, 20 miles to the north.
No injuries were reported.
After destroying the 169,000-square-foot mill building, the fire spread to stacks of finished lumber products on the site.
Ney says the ruins are expected to continue smoldering for several days.
