Valsetz
Valsetz was a timber company town that was established in 1919 and had a population of over 1000 in the mid-20th century. It was decommissioned by the company and destroyed in 1984. Today, you can still see some of the towns streets, the foundations of buildings and houses, and the remains of a large reservoir known as Lake Valsetz. The 37 mile drive from downtown Corvallis takes about 75 minutes (see route).
