What stands out about Thompson Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
After the timber boom of the late 19th century, Thompson Township's chief assets included second-growth trees such as balsam and aspen. The schooner Rouse Simmons, loaded with balsam Christmas trees, left Thompson Harbor for Chicago in November, 1912. The schooner sank with all hands off Two Rivers, Wisconsin, becoming one of the most famous shipwrecks in Lake Michigan history.
