Founded in 1944, Zip-o-log Mills is a family run sawmill business, owned and operated by third generation lumbermen James and Karl Hallstrom. The original sawmill was located near Coburg Oregon cutting 8' railroad ties. In 1951 our current site was purchased and a new mill was built at this location. Over the years there were many upgrades and modifications. The most recent project, completed in 2002, in addition to increased productivity and improved quality, has given us 52' capacity.
