About this map

The Penobscot River serves as the central artery for this 1915 survey of central Penobscot County, where the logging and rail economies intersect. The river corridor is flanked by the Maine Central Railroad, connecting riverbank settlements like Passadumkeag, Olamon, and Costigan. In the northwest, the Piscataquis River meets the Penobscot at Howland, a significant industrial junction near Montague.

Regional transportation is further defined by the Caribou Road and the Bangor and Aroostook Railroad cutting through Alton. Distinctive geological features such as the Horseback ridges run parallel to the river, while rural life is anchored by local institutions like the Scott Corners School and Spearin School. The map illustrates a landscape of organized townships and plantations, including Summit Plantation and Edinburg, during a period of established river-based commerce and expanding rail infrastructure.
