1984 Map of Black Calf Reservoir

USGS Topo · Published 1984

About this map

Bluff Creek and the surrounding drainage basins of northeastern Valley County define this landscape along the international boundary. This 1984 provisional survey illustrates the open, undulating terrain just south of the Canada-United States border, where Montana meets Saskatchewan. The topography is shaped by water movement across the plains, evidenced by the intricate contouring of Hardpan Coulee and the branching network of the East Fork Crow Creek. A central feature of the quadrant is the Black Calf Reservoir, a primary water source in this dry range country. The map serves as a detailed record of the township and range system at the edge of the nation, capturing the remote character of the northern Montana prairie before modern digital mapping standardizations.
