1986 Map of Fivemile Coulee West

About this map

The Principal Meridian bisects this high plains landscape of Toole County during the mid-1980s, revealing an area defined by its energy infrastructure and natural drainage patterns. The map documents an extensive Oil Field in the southwestern quadrant, supported by numerous Oil Well and Gas Well sites. This industrial development is overlaid upon a rugged system of coulees, including Twomile Coulee, Fivemile Coulee, and Black Coulee, which carve through the terrain toward Willow Cr in the northeast. The presence of multiple Pipelines and an Aqueduct underscores the complex management of resources in this arid environment, providing a technical look at the intersection of petroleum extraction and topographic features during this era of Montana’s history.
