About this map

The Maine and Quebec border, established along the watershed of the United States Canada international boundary, defines this mid-century landscape of timber tracts and deep water. The territory is organized into historic township blocks such as Penobscot Lake Town and Pittston Academy, reflecting a long history of industrial land grants. Navigation across the high country relies on a network of Private Roads and the Bald Mtn Trail, which leads to a Lookout Tower and Fire Warden Camp atop Bald Mtn.

The hydrography is dominated by the headwaters of the North Branch Penobscot River and the South Branch Penobscot River, which flow through a dense concentration of glacial ponds including Big Grenier Pond and the expansive Penobscot Lake. These waters, along with features like Canada Falls Lake and Dole Brook, supported the logging operations that defined Somerset County's economy during the 1950s.
