The Passadumkeag River snakes through this wilderness region along the border of Penobscot and Hancock counties, anchoring the small settlement of Saponac. The terrain is defined by dramatic glacial features and ridges, most notably the long esker known as The Horseback and the high elevations of Passadumkeag Mountain and Lord Mountain in the south. This area serves as a significant drainage basin for the Maine woods, where Madagascal Stream, Nicatous Stream, and Pistol Stream converge toward the river.
