The international boundary between Canada and the United States defines this Somerset County landscape, following the height of land along the western edge of the Maine wilderness. Rising to the south is Sandy Bay Mtn, a prominent peak that serves as a natural marker for the border. The terrain is characterized by the headwaters of significant regional drainage systems, including the S Br Penobscot River and W Br Sandy Stream. Infrastructure is minimal in this remote upland area, limited to the Campbell Pond Rd and the Alt-Main Trl, which provide the only managed access through the dense forests. This 2021 survey illustrates the topographical divide where water begins its journey toward the Penobscot, capturing the intersection of political boundaries and physical geography.
