The story

Gopher Ordnance could hold approximately 3,000 employees, however, most of the employees were not hired off site and had already worked in the defense industry. The plant was operated by DuPont. The production lines at Gopher were completed in 1943 and idled until 1944 when the government requested the plant begin production and create three additional production lines. The plant began production in January 1945, and was closed in October of the same year. The gunpowder being produced at the plant was being used for navy artillery shells. The smokestacks were for boiling water that was used to manufacture the gunpowder. The large T-Walls were part of solvent recovery houses. The process involved much volatile material.
