Sol G. Simpson and his family moved to Mason County in 1887, where Simpson worked laying ties and rails for the Port Blakely Mill Company's logging railroad. He formed S. G. Simpson Company in Matlock in 1890. Three of Simpson's brothers joined him in Mason County, and two of them worked for him. Simpson Logging Company opened its first sawmill, the Reed Mill, at Shelton in 1925. Numerous other mills and logging operations along the West Coast have been acquired by Simpson over the years.
