1917 Map of Passadumkeag

About this map

The Penobscot River serves as the central artery for this Penobscot County corridor during the early twentieth century, dictating the layout of settlements and transport. Along its banks, the Maine Central Railroad and Bangor and Aroostook Railroad parallel the water, connecting timber and trade hubs like Howland, Passadumkeag, and Costigan. The landscape is defined by the unique "horseback" glacial ridges and a complex network of islands, including White Squaw Island and Olamon Island, which split the river's flow. Local life is anchored by a system of rural educational outposts such as the Edinburg School and Spearin School, while the Enfield Sta highlights the importance of rail access to the remote township interiors. The map also captures several crossings including Spring Bridge and Boombridge, essential links between the isolated riverbank communities and the surrounding highlands like Vinegar Hill.
