2014 Map of Greenbush

About this map

The Penobscot River dominates this portion of Maine, carving a complex network of channels and islands including Sugar Island, White Squaw Island, and Thorofare Island. The river's historical importance is evident in the alignment of Main Rd and the Middle River Rd, which trace the eastern bank through the settlements of Greenbush and Costigan. Inland to the west, the landscape transitions into a more riparian environment defined by the meandering courses of Birch Stream and Hemlock Stream. Local history is anchored by several small burial grounds such as Alton Cem near the town of Alton and Cedarvale Cem further south. This survey illustrates the persistent rural character of Penobscot County, where modern infrastructure like the interstate corridor parallels long-established riverfront communities and tributary crossings.
