About this map

Lake Mason National Wildlife Refuge anchors the southern reaches of this landscape, where the prairie begins to break into the complex drainages of the Missouri River watershed. The terrain is defined by the sweeping contours of the Devils Basin, a prominent geological depression that dominates the eastern half of the survey. This 1986 record captures the industrial footprint of the era, marked by a concentrated cluster of Oil Wells situated within the basin's boundaries.
