1989 Map of Black Brook

USGS Topo · Published 1989

About this map

The Southwest Branch St John River carves through this remote northern landscape along the Quebec-Maine border during the late 1980s. This survey, grounded in data from the Canada-United States boundary, reveals a territory primarily defined by its hydrology and industrial resource extraction rather than permanent settlement. The watershed includes Black Brook and Norris Brook, which feed the river system as it flows through Big Six and T 7 R 19 W E L S. Local industry is evidenced by several excavations, including a Shale Pit and multiple Sand and Gravel Pits located near private access roads. The map provides a precise look at the international divide where Somerset County meets the MRC de Dorchester and the Canton de Metgermette-Nord in Quebec.
