Big Sioux River serves as the winding natural border between South Dakota and Iowa on this late 1960s survey, defining the rugged geography of Newton Hills. The landscape is dominated by the deeply eroded bluffs and timbered ravines of Newton Hills State Park, a stark contrast to the surrounding agricultural uplands. Evidence of the region’s rural development is visible in the network of country schools like Jensvold Sch and Moe Sch, alongside community anchors such as Trinity Ch and its accompanying North Trinity Cem.
