Rock Island sits just north of Washington Island at the outer edge of the Door Peninsula, guarding the Rock Island Passage — a critical shipping lane on Lake Michigan. Congress funded the original lighthouse in 1836 after petitions from Detroit merchants who needed reliable navigation aids for the passage. That first structure, a one-and-a-half-story house with a detached 30-foot tower, was poorly constructed and required replacement within two decades.
The existing limestone lighthouse was completed and first lit in 1858. It served a succession of civilian light keepers from 1836 through 1946, when the station was automated. David Corbin, appointed first keeper on December 19, 1837 (construction of the original tower began in 1836, completing in October 1837), served the station for fifteen years until his death in December 1852 and is buried in a small grave just outside the lighthouse — one of the most evocative details of any lighthouse on Lake Michigan.
The island changed hands multiple times before passing to Icelandic-American inventor Chester Thordarson, who constructed a Viking Hall boathouse on the island in 1929 using native stone. Thordarson's heirs sold the island to the State of Wisconsin in 1965 for the creation of Rock Island State Park, which admits no motor vehicles — access is strictly by foot and ferry. The Pottawatomie Lighthouse was listed on the National Register of Historic Places in 1979. A multi-year restoration was completed in 2004 by the Friends of Rock Island State Park in partnership with the Wisconsin DNR, returning the interior to its circa 1909–1913 appearance. Volunteer docents now live in the lighthouse seasonally and conduct free guided tours.

Thumping sounds from empty second floor of lighthouseDoors opening and closing without causeStrange noises throughout the lighthouseApparitions of children near Scandinavian settler cemeteryUnexplained footsteps and voices heard by campers
The Pottawatomie Lighthouse has accumulated ghost lore over nearly two centuries of occupation. According to Travel Wisconsin and regional coverage, visitors and volunteer docents report hearing strange thumping noises from the second floor when no one is upstairs, along with doors opening and closing without apparent cause. Local tradition holds that these phenomena are linked to David Corbin, the lighthouse's first keeper, who spent his final years at the posting and is buried just outside the building. Why Corbin would haunt his posting is never explained beyond his deep connection to the place.
Apart from the lighthouse itself, hikers on the island's perimeter trail encounter two cemeteries. The Scandinavian settler cemetery, associated with the Norwegian and Swedish families who farmed Rock Island in the late 1800s, has generated reports of apparitions of children playing together — a detail echoed in the Shadowlands index and regional ghost-lore compilations. A small Native American burial area on the island is also documented, though specific paranormal claims associated with it are not independently attested.
The island's extreme isolation — accessible only by two ferry rides, no motorized vehicles, 40 primitive campsites reached only on foot — contributes to its uncanny atmosphere. Campers report unexplained footsteps and voices at night.
