2011 Map of Shallows OE N

About this map

Lake Superior dominates the lower portion of this 2011 survey, which captures a critical maritime approach near the international boundary. The map provides a focused look at the waters leading toward the St. Marys River, with the Northwest Pier Light standing as a primary navigational aid for vessels transitioning between the open lake and the locks at Sault Ste. Marie. This specific cartographic study is primarily composed of the open water and navigational grid, serving as a precise record of the shoreline and maritime infrastructure along the northern edge of Michigan's Upper Peninsula during the early 21st century.
