The international boundary between Canada and the United States defines the northwestern limit of this topographic study, where the border follows the height of land between Frontenac County, Quebec, and the northern Maine frontier. The terrain is marked by the prominence of Sixtynine Mtn and the drainage patterns of the West Branch Gulf Stream and East Branch Gulf Stream. In this era, the area remained largely unincorporated timberland, divided into historical survey tracts such as Forsythe, Gorham Gore, and T 6 R 2 N B K P. Human activity is represented by a network of primitive routes, including a Jeep Trail and various other paths that navigate the slopes toward Turner Pond. The map illustrates the specific intersection of Somerset and Franklin counties along the international line, capturing a landscape dominated by watershed geography rather than permanent settlement.
