1949 Map of Spring Bay

About this map

Peoria Lake and the Upper Illinois River dominate this landscape at a time when the mid-century expansion of Peoria was beginning to climb the western bluffs. The river serves as a county divide, with the established community of Spring Bay on the eastern shore and the industrial and residential growth of Richwoods and Peoria Heights to the west. This survey illustrates the intricate terrain of the western riverbank, where narrow valleys like Moon Hollow and Strawberry Hollow cut through the high ground before meeting the river flats.
