About this map

The Rush River and its tributary, the South Branch Rush River, carve a meandering path through the agricultural landscape of northern Cass County. This 1967 topographic study reveals a terrain meticulously divided by section lines and civil boundaries, including the Traill Co Cass Co line at the northern edge. The map captures the meeting point of several rural townships including Greenfield, Hunter, Arthur, and Erie, illustrating the late-1960s spatial organization of this prairie region.

While largely dedicated to cultivation, the presence of a Gravel Pit along the South Branch indicates localized industrial activity tied to the land's geology. The survey also preserves the exact placement of fence and field lines as they appeared during 1965 aerial photography, providing a precise record of farmstead layouts and land use patterns during this era of North Dakota's agricultural history.
