1892 Map of Savanna

About this map

The Mississippi River creates a complex landscape of islands and channels in the late 19th century, serving as the defining border between Illinois and Iowa. The riverfront towns of Savanna and Sabula are established as critical junctions where rail meets water, specifically the Chicago Milwaukee and St. Paul Railroad which crosses the river here. The surrounding terrain of Carroll and Jo Daviess counties is characterized by deeply incised valleys and drainage systems like Rush Creek and the Plum River.
