1949 Map of Port Byron

About this map

The Mississippi River and Rock River define this 1940s landscape at the border of Illinois and Iowa, where early mid-century infrastructure meets long-standing rural settlements. This survey captures a dense network of one-room schoolhouses such as Shake-Rag Sch, Leafy Bower Sch, and Rose Hill Sch before the era of widespread school consolidation. The presence of the Old Indian Boundary Line running through the southern portion of the quadrangle highlights the enduring imprint of historical treaties on the physical geography of the region.
