1985 Map of Point Detour

About this map

Point Detour and the northern tip of Summer Island define this coastal landscape at the entrance to Big Bay de Noc in the mid-1980s. This transitional maritime zone is largely preserved within the Fairbanks Lake Superior State Forest, where the land meets the vast expanse of Lake Michigan. The map records an approximate mean lake elevation of 177.0 meters, providing a precise baseline for the shoreline as it existed during this survey period. With very little human development shown beyond township boundaries like t37n-r19w, the sheet emphasizes the natural geography of the Delta County coastline and its relation to the surrounding Great Lakes waters, including a small labeled portion of Lake Superior in the northwestern corner.
