About this map

The Mississippi River creates a complex landscape of islands and sloughs at the border of Carroll County and Jackson County in this late-nineteenth-century survey. The riverfront towns of Savanna and Sabula serve as the primary hubs, linked by the Chicago Milwaukee and St. Paul Railroad which crosses the waterway here. The terrain is deeply dissected by drainage systems like Straddle Creek and the Plum River, which flows through the Woodland and Mount Carroll townships.

Inland, the map reveals a network of small agricultural settlements such as Hickory Grove and Pleasant Valley. The presence of the Chicago Burlington and Northern Railroad running parallel to the river reflects the intense competition for rail dominance along the Mississippi corridor during this era of westward expansion. Local water bodies including Idens Lake and Dyson Lake punctuate the bottomlands south of the primary settlements.
