The North Branch Penobscot River and its accompanying Big Bog anchor the northern reaches of this Somerset County landscape. This territory is defined by the headwaters of the Saint John River system, featuring a chain of glacial water bodies including Lower First Saint John Pond, Second Saint John Pond, Third Saint John Pond, Fourth Saint John Pond, and Fifth Saint John Pond. The terrain rises sharply to prominent peaks such as Truesdale Mtn and Seboomook Mtn, while Summit Ridge provides a natural divide near Summit Pond. Movement through this interior forest is facilitated by the N Branch Access Rd, connecting various drainage basins like those of Sheehan Brook and Baker Stream. This map illustrates the hydrology of the Maine North Woods, where small streams like Austin Brook and Camp Brook feed the larger river systems.
