About this map

Lake Superior dominates the northern horizon of this Lake Superior shoreline study, where the Harbor of Refuge protects the settlement of Grand Marais. During the late 1960s, the area served as a critical maritime and aviation hub, anchored by the Radio Towers Coast Guard Station and the Grand Marais Airport. The landscape transition from the coast to the interior is defined by the Grand Sable State Forest and the eastern edge of the Pictured Rocks National Lakeshore.

Evidence of earlier industrial activity remains visible through the Old Railroad Grade winding through the forest near Sucker River. Geologists and local historians can trace the network of access routes like the Grand Marais Truck Trail and the Whitewash Jeep Trail, which navigate the terrain around Chipmunk Falls and Grand Marais Lake. The presence of numerous Gravel Pits suggests the ongoing importance of local mineral extraction during this era.
