1975 Map of Greenbush

About this map

The Penobscot River dominates this 1975 orthophotograph, winding through the heavily wooded terrain of central Maine. This aerial perspective, captured in the mid-1970s, reveals the intricate braided channels and islands of the river as it flows past the small settlements of Greenbush and Costigan. The map provides a unique visual record of the land use patterns of the era, where cleared agricultural plots and small homesteads contrast sharply against the dark canopy of the surrounding forests. Two primary waterways, Hemlock Stream and Birch Stream, drain into the river system, carving narrow paths through the landscape. The layout of roads and structures along the river corridor illustrates the historical reliance on this major waterway for transportation and settlement in Penobscot County.
