1984 Map of Coal Mine Creek West

About this map

Valley County, Montana, meets the Saskatchewan border in this mid-1980s topographical study of the high plains north of the Missouri River. The landscape is defined by the intricate dendritic drainage patterns of seasonal waterways, most notably the meandering course of South Coal Mine Creek and its southern tributaries. The map documents the international boundary where the United States and Canada meet, a transition from the rolling terrain of Valley County into the Canadian province of Saskatchewan. Small, local drainages like Tomato Can Creek and the North Fork South Creek carve through the northern Montana breaks, illustrating the hydrological network that sustains this sparsely settled ranching and mining region. This provisional edition preserves the precise elevations and landform data recorded during field checks in the late 1970s.
