Saint Martin Island and Rock Island stand as isolated outposts in the waters where Green Bay meets Lake Michigan. This 2022 survey documents the northern tip of Washington Island, specifically the area surrounding Jackson Harbor and the quiet wetlands of Little Marsh. The map reveals the intricate maritime geography of the Door County archipelago, tracing the deep channels of Saint Martin Island Passage and Rock Island Passage that have long guided vessels through these island chains. On Saint Martin Island, the presence of the Saint Martin Island Cem serves as a lone marker of local genealogy and past settlement amidst the surrounding Saint Martin Island Shoals. The interior of the islands is marked by contemporary road networks like Indian Point Rd and Gunnlaugsson Rd, alongside dedicated water trails for modern coastal exploration.
