About this map

Umbagog Lake dominates this late-twentieth-century landscape along the border of New Hampshire and Maine. The waters are divided into numerous inlets and points, including Thurston Cove, Sargent Cove, and Tidswell Point, with several prominent landforms such as Big Island and Bear Island rising from the lake. Along the eastern shore, the small settlement of Upton serves as a focal point near the winding Dead Cambridge riverway.

The map reveals a mix of recreational and industrial use, featuring Umbagog State Park alongside a Gravel Pit and numerous private timber or access roads. To the south, the terrain becomes increasingly steep toward Cambridge Black Mountain and the Hills near Mollidgewock Pond. This survey preserves the exact locations of local landmarks like the Cem at Upton and various state boundary markers, providing a clear record of the region's geography before further development.
