About this map

The Big Sioux River serves as the winding border between South Dakota and Iowa in this 1985 survey, defining the landscape and settlement patterns of the region. This transition zone features the established river towns of Canton and Hudson, which anchor the agricultural hinterland. The map reveals a highly structured grid of section lines and rural roads, characteristic of the upper Midwest, interspersed with significant conservation areas such as Newton Hills State Park and the uniquely named Gitchie Manitou State Game Production Area near the northern border.
