2011 Map of Thunder Bay Island
USGS Topo · Published 2011About this map
Thunder Bay Island Light stands as the primary navigational landmark in this maritime survey of the Lake Huron waters east of Alpena. The map is defined by a cluster of small islands that have long served as critical markers for shipping traffic entering the bay. Thunder Bay Island and its smaller neighbors, Sugar Island and Gull Island, appear here amidst the open expanse of Lake Huron. The isolation of these landforms from the Michigan mainland highlights their historical role in Great Lakes maritime safety, with the light station acting as a sentinel for the rocky shallows and shipping lanes that define this portion of the coastline.
