1971 Map of Marietta

About this map

Marietta and Nassau anchor this 1970s landscape on the Minnesota and South Dakota border, illustrating the rural character of Lac qui Parle County and Grant County. The region's agricultural and transit history is visible through the Burlington Northern line and an Old Railroad Grade running west from Marietta. Significant local landmarks like the Swedish Mission Ch and Augusta Cem provide valuable points of reference for genealogists tracking early prairie settlements. The geography is defined by the winding South Fork Yellow Bank River and several wetlands, including Kaufman Slough and Pegg Lake. Much of the southern and western portions of the quadrangle are dedicated to a National Waterfowl Production Area, highlighting the conservation of the local prairie pothole ecosystem amidst numerous gravel pits and township boundaries like Adams and Vernon.
