2018 Map of Washington Island NE

About this map

Washington Island and Rock Island dominate this coastal survey of the maritime boundary between Wisconsin and Michigan. The landscape is defined by the strategic passages connecting Green Bay to Lake Michigan, specifically Rock Island Passage and Saint Martin Island Passage. Evidence of early isolated settlement is visible on Saint Martin Island, where the Saint Martin Island Cem sits near the shores of South West Bay. On the northern tip of Washington Island, a network of local roads such as Old Indian Point Rd and Jackson Harbor Rd lead toward Jackson Harbor, reflecting the island's established community and its reliance on the protected waters of the harbor. The map also identifies hazardous underwater features like Saint Martin Island Shoals and Fisherman Shoal, which were critical to the navigation of these Great Lakes shipping lanes.
