1970 Map of Kaskaskia

About this map

Kaskaskia Island and the complex riverine borderlands between Illinois and Missouri are documented here during the late 20th century. The unique geography of the area, shaped by the shifting Mississippi River, includes remnants of early settlement like Old Kaskaskia and the modern village of Kaskaskia. To the north, Fort Kaskaskia State Park overlooks the confluence where the Kaskaskia River meets the Mississippi near a modern Lock and Dam. The landscape is a network of sloughs and alluvial features, such as Mitchell Slough and Moro Island, punctuated by small communities like Reilly Lake and Dozaville. Researchers will find significant genealogical markers including Kaskaskia Cem and St Marys Ch, alongside rural infrastructure like School No 124 and the Delassus Landing Field, illustrating the persistence of river-town life amidst a dynamic flood plain.
