USGS Topo · Published 1972About this map
Kaskaskia Island is the centerpiece of this Mississippi River landscape, defined by its complex hydrology and historical shifts in the state boundary. Unlike most of Illinois, this area sits west of the current main channel of the Mississippi River, creating a unique geographical pocket where Old Kaskaskia and the modern settlement of Kaskaskia reside. The terrain is marked by remnants of former river paths, such as the Slough and Idlewild Island, which illustrate the volatile nature of the river before modern stabilization.
