What stands out about Marine on St. Croix’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Marine on St. Croix was founded in 1839 as Marine Mills. The city was the site of the first commercial sawmill on the St. Croix River. The sawmill was built by Illinois lumbermen David Hone and Lewis Judd, who saw the opportunity to cut the St. Croix River valley's abundant white pine. They named the mill after their hometown of Marine, Illinois. The mill began operation in August 1839, making it the first commercial sawmill within Minnesota. It was first powered by water and then by steam, and it operated through 1895. Over 197,000,000 board feet (460,000 m3) of lumber was milled through this sawmill. Although the frame buildings were demolished and the sawmill equipment was sold, footings of the buildings are still visible. The Marine Mill site is now a historic site operated by the Minnesota Historical Society.
