The West Branch Moose River is a short tributary of the South Branch Moose River in Franklin County, Maine. Its source (45.4328°N -70.6294°W) is on Caribou Mountain in Merrill Strip (Maine Township 2, Range 7, WBKP), about 2000feet from the Canada–United States border, which runs along the height of land between the watersheds of the Kennebec River in Maine and the Chaudière River in Quebec. From there, the river runs [1] northeast to its confluence with the Moose River's South Branch in Skinner (T1, R7, WBKP).
