2021 Map of Black Brook

About this map

The Canada-United States border defines the western edge of this Somerset County landscape, where the international boundary follows the winding course of the Southwest Branch Saint John River. This remote forested interior is dominated by the headwaters of the Saint John drainage system, including the extensive Little Southwest Branch Saint John River and its tributary, Black Brook. The terrain is marked by a network of logging and access routes, such as Baker Lake Rd, Dump Rd, and 300 Rd, which navigate the high ground between the various river branches. The map provides a detailed view of the drainage patterns at the very edge of the Maine North Woods, where the eastern branch of E Br Norris Brook begins its descent, illustrating the rugged hydrologic connections that define this borderland region.
