Barnum Island is a small l4.5-acre land mass located on the southwestern end of the Isle Royale archipelago. The 1910 Large Barnum Boat House, the 1933 Small Barnum Boat House, and the 1892 Johns Family Log cabin are part of the Barnum resort colony and eligible for listing on the National Register of Historic Places as part of the Barnum Island Historic District. The Large Boat House is roughly 30 feet by 40 feet, rests on timber piers and cribbing, and is surrounded by water on all four sides. It has a log frame, gable-on-hip roof, and half log vertical log siding and horizontal board siding. The Small Boat House is roughly 18 feet by 24 feet with a gable roof and is also supported on timber cribbing surrounded by water. The Johns Log Cabin is approximately 16 feet by 22 feet, one-and-one-half-story, with horizontal round log walls and a gable roof with shingled gable ends. It is situated near a steep eroded bluff on the island’s south shore. The goal of the Historic Property Project Documentation (HPPD) for the Large Barnum Boathouse, Small Barnum Boathouse, and Johns Log Cabin is to synthesize historical information and facility maintenance data to support future stabilization and rehabilitation projects. The accompanying Treatment Plan furnishes a feature condition assessment and outlines a conceptual plan for preservation with associated Class C construction cost estimates. Isle Royale National Park was established as a Unit of the National Park Service on April 3, 1940, to set apart a remote island archipelago and surrounding waters in Lake Superior as a national park for the benefit and enjoyment of the public and to preserve and protect its wilderness character, cultural and natural resources, scenery, and ecological processes. Additionally, as a unit of the national park system, Isle Royale National Park provides opportunities for recreation, education and interpretation, and scientific study.
