1975 Map of Decorah 2 NW

About this map

Upper Iowa River meanders sharply through this landscape of the mid-1970s, carving deep loops into the rural terrain of Winneshiek County. This orthophotograph, prepared from high-altitude aerial imagery, reveals the complex agricultural patterns and wooded riverbanks that define the region. The small settlement of Bluffton sits tucked along a southern bend of the waterway, appearing here as a cluster of buildings and crossroads during a period of steady Midwestern farming activity. The stark black-and-white imagery, provided through the Iowa Geological Survey, highlights the division between cultivated fields and the natural floodplain, offering a precise view of land use and river morphology before modern development altered these rural corridors.
