About this map

The Appalachian Trail winds through this mid-century wilderness in Piscataquis County, crossing a landscape defined by an extensive network of remote ponds and high peaks. Centered on Jo-Mary Mtn, the terrain is marked by dozens of water bodies including Nahmakanta Lake, Pemadumcook Lake, and Lower Jo-Mary Lake. The survey reveals the early infrastructure of fire prevention and land management, featuring a Lookout Tower atop Wadleigh Mountain.

This area is organized by historic township designations such as T 1 R 11 and T A R 10, reflecting the large-scale land grants like College T 7 R 10 and Bowdoin that shaped North Maine Woods ownership. Prominent ridges like Potaywadjo Ridge and peaks including White Cap Mtn and Big Boardman Mtn create a complex topography of valleys where drainage systems like Tumbledown Dick Brook and Farrar Brook connect isolated ponds.
