South Arm serves as a lone settlement hub at the southern reach of Lower Richardson Lake, marking a transition between the water-bound transport of the Richardson Lakes and the timberlands of the interior. The landscape is defined by a series of prominent peaks and high ridgelines, including Metallak Mtn, Elephant Mtn, and Bemis Mtn, which form a natural corridor for the Appalachian National Scenic Trail. This famous path winds through the eastern portion of the map, crossing over the heights of Old Blue Mtn. A network of drainage systems like Metallak Stream and Mosquito Brook feed into the massive reservoirs of Upper Richardson Lake and Mooselookmeguntic Lake. The presence of Toothaker Island and Metallak Island highlights the intricate shoreline and navigational character of these connected northern Maine waterways.
