About this map

Portage Entry sits at the strategic mouth where the Portage River meets the expansive waters of Keweenaw Bay. This coastal landscape is defined by its maritime infrastructure, including the Portage River Harbor of Refuge, which serves as a vital point of transit for vessels navigating the Upper Peninsula's northern shores. To the east, the settlement of Jacobsville anchors the shoreline, historically known for its sandstone, while the nearby White City marks the sandy peninsula's tip.

Inland, the terrain transitions into a grid of rural communities and family-named homesteads. Small clusters like Klingville, Arnheim, and the areas of Korhonen and Helberg are connected by a network of local roads such as Old Timers Rd and Sutinen Rd. The map traces the winding paths of Snake River and Jarvi Creek, illustrating a landscape where natural drainage patterns and the lakefront have dictated the development of roads and residential pockets across the Houghton and Baraga county line.
