Logging and the lumber industry were staples of the early economy in Sister Bay.  There was a major sawmill on the waterfront in Sister Bay, but some farmers also maintained their own mills to provide lumber for themselves and their neighbors.  This 100+ year old sawmill belonged to Hjalmar Holand, noted Door County historian and author, who owned property in the area that became Peninsula State Park.  The sawmill may have been used in the park; it was donated by Holand’s granddaughter, Barbara Nelson.
