World's Largest Mill Historical Marker Potlatch, ID

The Potlatch Lumber Company was founded in 1903. In 1900, Frederick Weyerhaeuser and other investors bought white pine forestland in North Central Idaho. In 1906, the company created its first sawmill along the Potlatch River. The area around the mill became a company town. The mill grew to become the largest white pine mill in the world. It would hold this title for 20 years.

In 1926, the Clearwater Timber Company, which was also founded by Weyerhaeuser, would create the Clearwater Mill in Lewiston, ID. It would take over the title of the world’s largest white pine mill from Potlatch.

Company Town, Potlatch, Idaho Historical Marker

Started as a company town for Potlatch Forest, Inc., it was founded by Frederick Weyerhaeuser and several other investors in 1900. By 1906, the town had the world’s largest White Pine sawmill. The sawmill was located on the Potlatch River.

During World War II, the company helped with the war efforts. After the war, with a booming housing market, Potlatch Forest, Inc. built a plywood plant in Lewiston, Idaho. It continued to grow throughout the 1950s and 1960s.

By the 1980s, however, the company began to struggle with the fluctuations in the housing market. It attempted to modernize during the 1980s and 1990s. In 2018, however, it merged with Deltic Timber with the consolidation’s new name being PotlatchDeltic Corporation.

With the closure of the sawmill, the town has seen a dramatic drop in population.

Built as a model town, Potlatch was owned by Weyerhaueser’s Potlatch Lumber Company.

Spokane architect C. Ferris White designed the new community in 1905. Workers’ housing stood close to the mill. Managers’ homes were built away from the plant’s noise and smoke. The railroad depot separated town from industry. All company owned, Potlatch was complete with churches, school, gym, hospital, opera house, and company store.
