About this map

Portage River serves as the focal point of this coastal landscape, where the waterway meets the expansive waters of Lake Superior. The settlement patterns here are deeply tied to the shore, with Portage Entry and Jacobsville flanking the river's mouth. This 2017 data reflects a region where maritime history and local family roots intersect, evidenced by numerous named roads like Kokko, Korhonen, and Virenius Rd that suggest long-standing homesteads.

Further inland, the transition from the wetlands of Arnheim to the shoreline terrain of Singing Sands illustrates the diverse ecology of the Keweenaw Peninsula's eastern edge. The map captures the infrastructure of the Portage River Harbor of Refuge, a critical safety feature for vessels navigating Keweenaw Bay. Small clusters such as Klingville and the landing at White City provide a detailed look at the rural character of Baraga and Houghton counties before they meet the open water.
