1960 Map of Washington Island

About this map

Washington Island stands as the central anchor of this Door County maritime landscape, connected by ferry across the treacherous Porte Des Morts Passage. The 1960 field check captures a community defined by its natural harbors, such as Detroit Harbor and Jackson Harbor, and a scattering of inland Gravel Pits reflecting local infrastructure. Notable landmarks like the Pottawatomie Light on Rock Island and the Washington Island Landing Field highlight the island's role as a navigational hub at the mouth of Green Bay. Significant natural preserves including the Green Bay National Wildlife Refuge and Coffer Swamp illustrate the varied terrain of the archipelago. For local historians, the inclusion of Trinity Ch and the remote St Martin Cem on St Martin Island provides vital data on early settlements and community life across the scattered islands of the Rock Island Passage.
