The Iowa River carves a winding path through the heart of Marshall County, shaping the agrarian landscape between Green Mountain and Le Grand. This modern survey documents the intricate network of township roads and county highways that stitch together the central Iowa prairie, reflecting a settlement pattern established by 19th-century pioneers. The map is particularly rich for genealogical research, identifying numerous small burial grounds such as the Iowa River Brethren Cem, Wallin Cem, and the Le Grand Friends Cem.
