1980 Map of Black River Harbor

USGS Topo · Published 1981

About this map

Lake Superior borders the northern edge of this coastal survey, where the Black River meets the harbor in the Ottawa National Forest. This landscape is defined by its dramatic series of water features as the river descends toward the lake, passing over Rainbow Falls, Sandstone Falls, Gorge Falls, and Potawatomi Falls in quick succession. Further upstream, Manabezho Falls and Great Conglomerate Falls mark the river's path through the wooded terrain.
