1966 Map of Ethridge NW

USGS Topo · Published 1969

About this map

The high plains of Northern Montana are defined by the sharp topographical descent along the Glacier Co Toole Co border, where the land drops away into a complex network of drainage basins. This mid-1960s survey reveals an industrial landscape driven by resource extraction, featuring numerous Gas Wells and Oil Wells scattered across the plateau. The infrastructure of the era is clearly marked by a prominent Pipeline and a central Pumping Sta, illustrating the logistical effort to move fuel from this sparse region. In addition to the energy sector, the map documents the natural erosion patterns of the area, including the carved path of Maids Coulee and the broad reach of Sand Coulee. These features represent the typical drainage systems of the Toole County landscape before modern development significantly altered the rural terrain.
