Forty Mile Point Lighthouse is an active lighthouse on the western shore of Lake Huron in Alcona County, Michigan near the community of Harrisville, Michigan and the Alpena, Michigan region. Constructed in 1896 during a period of expanding Great Lakes navigation, the station guided steamers and schooners along a hazardous stretch of coastline between Thunder Bay Island Light and Au Sable Point Light Station. The lighthouse and attached keeper's quarters now form the core of a state park and museum preserving maritime heritage from the late nineteenth and early twentieth centuries.
Construction of the station responded to increased traffic tied to the lumber, shipping, and Great Lakes shipping industries after the National Lakeshore era of expansion and the consolidation of routes near Saginaw Bay. The United States Lighthouse Board authorized the light in the 1890s amid a wider program that also produced facilities at Granite Island Light and Sturgeon Point Light. The tower and keeper's house were completed in 1896 under plans drawn by Board engineers influenced by designs used at Marquette Harbor Light and Point Iroquois Light. Early keepers logged rescues and maintenance during storms associated with the Great Lakes Storm of 1913 and the seasonal navigation of timber-laden schooners and iron ore carriers plying routes to Detroit and Cleveland, Ohio. During the twentieth century, board administration shifted to the United States Lighthouse Service and later to the United States Coast Guard, which automated many lights in the mid-1900s. Local civic groups and historical societies including the Alcona Historical Society and volunteers later campaigned to preserve the structure as maritime tourism and heritage interest expanded.
The lighthouse complex exhibits late Victorian masonry techniques typical of lights constructed by the United States Lighthouse Board. The conical brick tower sits on a stone foundation adjacent to a -story brick keeper's dwelling connected by a brick workroom and oil house. Architectural details echo elements found at Miner's Castle-era structures and follow standardized plans used at Big Sable Point Light and Point Betsie Light. Exterior materials include locally sourced brick and dressed stone; interior fittings originally included hardwood floors, cast-iron stoves, and built-in cabinetry similar to fixtures cataloged in inventories for the Ludington North Breakwater Light. The site layout takes advantage of a promontory offering visibility to vessels bound for Thunder Bay and the Straits of Mackinac corridor.
Forty Mile Point was equipped with a fourth-order Fresnel lens—an optical technology pioneered in nineteenth-century France and widely adopted by the United States Lighthouse Board. The lens assembly concentrated light from a kerosene-fueled lamp (later replaced by electric lamps) into a focused beam visible for many miles across Lake Huron. The lens type and lantern room closely resemble those installed at Au Sable Point Light Station and Eagle Harbor Light. Maintenance routines required polishing of prisms, wick trimming, and clockwork winding to rotate the lens in non-electrified systems, work documented in logs comparable to those kept at Round Island Lighthouse and Old Presque Isle Light. Upgrades over time followed patterns seen in Point Betsie Light and other Great Lakes beacons as electrification and automated lamp changers reduced keeper labor.
Keepers at the station served under the United States Lighthouse Service and later the United States Coast Guard, with tenures that often reflected the itinerant nature of maritime service in the Great Lakes. Notable figures in keeper lists mirror the careers of contemporaries at Shelldrake Point Light and Sturgeon Point Light, administering fog signals, inspecting mooring hardware, and recording weather conditions used by regional shipping interests like those based in Alpena and Saginaw, Michigan. Operations included fuel management, tower maintenance, and coordination with passing freighters from ports such as Duluth, Minnesota, Toledo, Ohio, and Gary, Indiana. During winter months supply lines relied on railheads in Oscoda, Michigan and roadways connecting to I-75 corridors further south.
Preservation efforts were spearheaded by local historical societies and park authorities, following patterns seen in restorations at Whitefish Point Light and Marquette Harbor Light. Restoration work addressed masonry repointing, roof replacement, and conservation of the original fourth-order lens and lantern room glazing—projects funded through state grants, private donations, and volunteer labor modeled after campaigns at Henry Ford Museum-affiliated sites and regional heritage trusts. The transfer of property to state management allowed the creation of interpretive exhibits and stabilized the complex against erosion common to Lake Huron shorelines. Archaeological assessments and archival research paralleled investigations at Michigan State Historic Preservation Office-reviewed sites.
The lighthouse is accessible via Forty Mile Point Light State Park, which provides trails, picnic areas, and shoreline viewing opportunities similar to visitor amenities at Huron National Forest recreation sites and Negwegon State Park. The keeper's house serves as a museum exhibiting period artifacts, shipwreck photographs from nearby wreck sites like those recorded in the Thunder Bay National Marine Sanctuary, and interpretive panels on Great Lakes navigation. Seasonal programs, volunteer docent tours, and educational outreach collaborate with institutions such as the Great Lakes Shipwreck Museum and local schools in Alcona County and Iosco County to promote maritime history and coastal ecology.
The lighthouse occupies a place in regional maritime identity akin to the cultural prominence of Whitefish Point and Port Austin landmarks, featuring in photographic portfolios by artists who document Great Lakes heritage and appearing in local festival materials and tourism literature produced by Pure Michigan campaigns. It figures in narratives about shipwrecks, navigation lore, and conservation featured in regional publications and media that also cover sites like Point Betsie Light and Big Sable Point Light Station. The structure and grounds are used for community events, historical reenactments, and outreach programs that link to broader preservation movements encompassing National Trust for Historic Preservation-affiliated efforts and state heritage initiatives.
